PS20060 data sheet figure 3 - detailed block diagram 1.0 functional description the PS20060 is a three-band rf mixer oscillator with on-board frequency synthesizer and if agc amplifier, integrating all tuner active circuitry after the tracking filter into a single package. it is intended for use in all band terrestrial tuners, and requires a minimum external component count. it contains all elements required for rf down conversion to a standard if with the exception of external vco tank circuits. in normal applications the rf input is interfaced to the selected mixer oscillator preamplifier through the tuner pre- filter and agc stages. the PS20060 provides an rf agc control signal, which can be used to control the rf gain. the preamplifier output feeds the mixer stage where the required channel is down converted to the if frequency. the local oscillator frequency for the down conversion is obtained from the on board pll and local oscillator, with an external varactor tuned tank. the downconverted signal is then passed through an external filter into a saw filter driver amplifier. this provides two output channels for hybrid analog and digital applications. data sheet 291359 issue 1 plessey semiconductors ltd. design & technology centre, delta 500, delta business park, great western way, swindon, uk sn5 7xe tel: +44 1793 518000 fax: +44 1793 518030 web: www.plesseysemi.com 7
PS20060 data sheet an agc if amplifier is included which provides an output signal to a digital demodulator. the device is controlled through an i 2 c compatible interface. 1.1 rf converter the PS20060 contains three input stages to cover the vhf1, vhf3 and uhf frequency bands. the inputs would normally be driven by front end amplifiers and tracking filters. all three inputs are differential, however, the vhf1 and vhf3 inputs would normally be driven single ended. these inputs therefore can share a common input reference pin. the uhf input should be driven with a differential signal. the inputs are all high impedance. the differential converter if output is then passed through an external interstage filter. this can be tuned for 36 mhz for dvb-t applications but can also be used at 44 mhz and 57 mhz to be compatible with other tv standards. the recommended filter circuit is shown in figure 11. the design of this filter provides an impedance transformation as well as rejection of adjacent channels. a 0.5 db chebychev filter with 10 mhz bandwidth is recommended. this gives a flat response across the pass band and takes into account normal component tolerances. 1.2 saw driver amplifier the output of the interstage filter then passes to the saw filter drive amplifier. this provides further amplification and interfaces to the saw filter. two saw filter drive outputs are provided for hybrid analog and digital applications. both output stages are identical, however, the digital output (sd, sdb) should always be used for digital applications, as the pin out of the device has been optimized to give the best isolation performance in this configuration. output selection is programmable however it should be noted that the unselected output is not powered off but operates at a lower power level which means that a signal will still be present on the output, but with reduced output drive capability. the differential outputs will drive a balanced saw filter with a tuning inductor to resonate with the saw filter input capacitance. the saw filter can also be driven without the tuning inductor but this requires the addition of 360 ohm resistors to ground on the saw driver outputs to increase the output drive capability. this will increase total current consumption by approximately 14 ma. 1.3 agc detector and adc the PS20060 contains a broadband agc detector circuit which provides an output to provide gain control for the rf frontend gain stages. the detector input signal is derived from the signal level in the saw driver amplifier. the composite signal at this point is the wanted signal plus adjacent channels (n +/- 1, n +/- 2, n +/- 3). the agc detector threshold point at which the agc output becomes active can be programmed to one of eight levels via the i 2 c interface. when the composite level reaches the agc threshold, the agc output pin will be active. the agc attack current is fixed, however, the decay current can be programmed to two levels. the agc output can only drive a high impedance e.g., a dual gate fet. if rf gain control uses a pin diode then a simple buffer circuit will be required. an agc flag output is also available through the i 2 c interface. this indicates when the agc output is active i.e., less than 4 volts. the agc output level can also be monitored by an on chip 3 bit adc. although the adc is 3 bits, only 5 levels are available. alternatively the adc can be programmed to measure the voltage on an external pin (adc pin 4). 1.4 if agc amplifier the agc amplifier amplifies the output of the saw filter for the digital channel and provides a differential output to the demodulator. the analog gain control signal is normally derived from the demodulator. at least 41 db of gain control is provided. the agc amplifier can be powered down independently of the rest of the device if not required. this mode could be used in analog applications to reduce overall power consumption. data sheet 291359 issue 1 plessey semiconductors ltd. design & technology centre, delta 500, delta business park, great western way, swindon, uk sn5 7xe tel: +44 1793 518000 fax: +44 1793 518030 web: www.plesseysemi.com 8

PS20060 data sheet figure 6 - mid band (vhf3) external tank circuit figure 7 - high band (uhf) external tank circuit 1.6 pll frequency synthesizer the pll frequency synthesizer section contains all the elements necessary, with the exception of a frequency reference and loop filter to control a varicap tuned local oscillator, to form a complete pll frequency synthesized source. the device allows operation with a high comparison frequency and is fabricated in high speed logic, which enables the generation of a loop with good phase noise performance. it can be operated with comparison frequencies appropriate for frequency offsets as required in digital terrestrial (dtt) receivers. the lo input signal from the selected oscillator section is routed to an internal preamplifier, which provides gain and reverse isolation from the divider signals. the output of the preamplifier interfaces directly to the 15-bit programmable divider, which is of mn+a architecture, with a 16/17 dual modulus prescaler. the a counter is 4-bits, and the m counter is 11 bits. the output of the programmable divider is fed to the phase comparator together with the comparison frequency, which is derived either from the on-board crystal controlled oscillator, or from an external reference source. in both cases the reference frequency is divided down to the comparison frequency by the reference divider, which is programmable into 1 of 16 ratios. the output of the phase detector feeds a charge pump and loop amplifier section, which when used with an external loop filter, integrates the current pulses into the varactor control voltage. test modes allow both the divider outputs to be monitored via output port gpp0 for debug and test purposes. lmopb lmop vvar r_bias r_bias cs pf l1 nh lhipb lhopb lhop lhip vva r r_bias r_bias cs pf l1 nh cp r_damp cp cp cp data sheet 291359 issue 1 plessey semiconductors ltd. design & technology centre, delta 500, delta business park, great western way, swindon, uk sn5 7xe tel: +44 1793 518000 fax: +44 1793 518030 web: www.plesseysemi.com 10
PS20060 data sheet the pll includes a lock detect circuit. the lock detect output is available by reading the status byte on the i 2 c interface 1.7 general purpose switching ports the PS20060 has four output switching ports. three of these ports (gpp[3:1]) incorporate a 10 kohm pull up resistor. the remaining port (gpp0) is an open collector switch. these ports can be used for switching external rf input stages for example. ports gpp[1:0] can also be used as test outputs for debug purposes. 1.8 i 2 c interface the PS20060 is controlled by an i 2 c data bus and is compatible with both 3.3 v and 5 v control levels. data and clock are fed in on the sd a and scl lines respectively as defined by i 2 c bus format. the device can either accept data (write mode), or send data (read mode). the lsb of the address byte (r/w) sets the device into write mode if it is low, and read mode if it is high. the device can be programmed to respond to 1 of 4 addresses, which enables the use of more than one device in an i 2 c bus system. the address is selected by applying a voltage to the ?add? input. when the device receives a valid address byte, it pulls the sda line low during the acknowledge period, and during following acknowledge periods after further data bytes are received. when the device is programmed into read mode, the controller accepting the data must pull the sda line low during all status byte acknowledge periods to read another status byte. if the controller fails to pull the sda line low during this period, the device generates an internal stop condition, which inhibits further reading. data sheet 291359 issue 1 plessey semiconductors ltd. design & technology centre, delta 500, delta business park, great western way, swindon, uk sn5 7xe tel: +44 1793 518000 fax: +44 1793 518030 web: www.plesseysemi.com 11
PS20060 data sheet 2.0 programming the PS20060 is fully programmable through the i 2 c interface. the device can also output data to the controller. 2.1 programmable features 2.2 register map there are a total of 7 write registers, the first of which is the address register. the control registers are described in detail in the following section. the msb of each register is written first. after reception and acknowledgement of a correct address (byte 1), the msb of the following byte determines whether that byte is interpreted as a byte 2 or byte 4; a logic '0' indicating byte 2, and a logic '1' indicating byte 4. the next data byte will then be interpreted as byte 3 or byte 5 respectively. byte 5 can be followed by byte 6 and byte 7 if required. a stop condition can be generated after any data byte, however, if it occurs during a byte transmission, the previous byte data is retained. to facilitate smooth tuning, the frequency data bytes are only accepted by the device after all 15 bits of frequency data (i.e. bytes 2 and 3) have been received, or after the generation of a stop condition. it should also be noted that if it is necessary to program bytes 6 or 7, then bytes 4 and 5 must be programmed at the same time table 2 - programmable features feature description rf programmable divider programs pll main divider reference programmable divider programs pll reference divider to set required frequency step band selection selects rf input and appropriate lo oscillator. agc threshold sets the input power level threshold at which the agc detector starts to generate a control level. agc decay sets the agc decay current. charge pump current selects one of the four charge pump current settings. if amplifier function the if amplifier can be enabled independently of other circuit blocks. sawf output select select the analog or digital saw driver output. ports gpp[3:1] these are configured as npn buffers with 10 kohm pull-up resistors to v cc . logic ?1? = on logic ?0? = off; default on power up port gpp0 this is configured as a npn open collector buffer. logic ?1? = on logic ?0? = off; default on power up vco trim adjusts the vco bias current to provide optimum phase noise performance. adc input select select either the internal agc detect output level or the external level applied to the adc input pin. programmable power the PS20060 has various power saving modes. test modes test modes to monitor and control internal pll signals. data sheet 291359 issue 1 plessey semiconductors ltd. design & technology centre, delta 500, delta business park, great western way, swindon, uk sn5 7xe tel: +44 1793 518000 fax: +44 1793 518030 web: www.plesseysemi.com 12

PS20060 data sheet the low (vhf1) and mid (vhf3) bands are single ended however the high band (uhf) should be differential. all if signals are differential. it is essential to have good rf layout around the rf stages, i.e., rf inputs and the vcos. track lengths around the vco?s should be minimized to reduce track inductance. the layout should be organized to give good isolation between the if signal paths. in particular good isolation is required between the outputs and inputs of the if agc amplifier. isolation across the saw filter is also important to ensure rejection of unwanted adjacent signals. this can be achieved by routing input and output tracks on opposite sides of the board. it is also important to have good isolation between the high level if signal and the crystal oscillator circuit to minimize any interactions. care should be taken when locating if tuning inductors to ensure there is no radiation to other parts of the circuit. the crystal oscillator can also provide a clock signal to the demodulator. this can be done by taking the oscillator signal from the crystal series capacitor (27 pf) as shown in the following diagram. figure 10 - crystal oscillator circuit (4 mhz) 150pf 27pf 47pf xcap xtal to demodulator data sheet 291359 issue 1 plessey semiconductors ltd. design & technology centre, delta 500, delta business park, great western way, swindon, uk sn5 7xe tel: +44 1793 518000 fax: +44 1793 518030 web: www.plesseysemi.com 23
PS20060 data sheet the interstage filter between the converter outputs provides some rejection of adjacent channels (n +/- 2).the recommended values are shown in figure 11. the choice of components is important not only to give a flat response but also to provide an impedance transformation. the specified noise figure for the low and mid bands assumes that there will be a network before the device to provide image rejection. in a tuner this would be part of the input tracking filters but for test purposes a network is shown in figure 12. figure 11 - interstage filter cnopb cnop sipb sip l1 l1 cc cc l2 c1 c1 rterm rterm sawf drive amplifier input c2 r source r source vcc c1 type if 0.5 db bw component values mhz mhz r source r term l1 l2 c1 cc c2 0.5 db chebychev 36 10 500 250 680 680 12 18 12 0.5 db chebychev 44 10 500 250 390 390 22 15 7.5 data sheet 291359 issue 1 plessey semiconductors ltd. design & technology centre, delta 500, delta business park, great western way, swindon, uk sn5 7xe tel: +44 1793 518000 fax: +44 1793 518030 web: www.plesseysemi.com 24
