11 detailed description the max2090 is a high-linearity analog vga designed to interface with 50 i systems operating in the 50mhz to 1000mhz frequency range. an external analog con - trol voltage controls the analog attenuator. the device features a gain range of -10.9db to +26.1db, a noise figure of 4db, oip3 linearity of +38dbm, and a wide rf bandwidth. each of these features makes the device an ideal vga for numerous receiver and transmitter appli - cations. in addition, the device operates from a single +5.0v supply. applications information modes of operation the device can operate in several different modes, as summarized in table 1 . vga-only mode operation vga-only mode operation consists of setting ctrl1 = logic 1 and ctrl2 = logic 0, and applying a dc value to plvlset between 0 and 2.5v dc to manually adjust the attenuator and subsequently the rf_out power to any desired value. the output power at rf_out increases at a rate of 19.5db/v as plvlset is increased. the error ampli - fier and alarm are powered off in this mode, reducing the supply current by 10ma typical. in vga-only mode, com - ponents r5, r7, c8, c9, and c16 can be left unpopulated. closed-alc mode operation closed-alc mode operation consists of setting ctrl1 = ctrl2 = logic 1. in this mode, the det_in input is driven from an external detector through r7. ideally, a power detector with an output voltage range of 0.1v to 2.4v dc is recommended, but the max2090 operates with any detector whose output ranges from 0 to 2.5v dc. plvlset is used to set the rf out power by comparing it to the det_vin (pin 8) voltage in the error amplifier. as plvlset increases, the power at rf_out also increas - es. components r5, c8, and c9 are installed to set the response time of the loop. see the typical application circuit . this loops acts to maintain the input power to the external detector by driving the attenuator in servo fashion as the power level into rf_in changes. plvlset can be externally driven to a dc value between 0 and 2.5v, such that the desired power is present at rf_out. control inputs the max2090 has four control inputs: ctrl1, ctrl2, alm_thres, and plvlset. v cc must be present before voltages are applied to these pins. in cases where this is not possible, a 200 i resistor must be included in series with the control inputs to limit on-chip esd diode conduction. ctrl1 and ctrl2 are 3v logic controls and cannot be driven from 5v logic. in the case where no logic control is available and a logic-high is required, a voltage-divider can be used from the 5v v cc supply to produce the 3v logic-high. table 1. mode control logic ctrl1 ctrl2 vga error amplifier alc loop alarm function description 0 0 disabled disabled disabled disabled power-down mode 1 1 enabled enabled enabled enabled closed-alc mode: alc loop locks det_vin to plvlset 1 0 enabled disabled disabled disabled vga-only mode 0 1 factory test mode (do not use) maxim integrated max2090 50mhz to 1000mhz analog vga with threshold alarm circuit and error amplifier for level control
12 table 2. typical application circuit component values note: the checkmarks in the mode of operation columns indicate that the component is used within each respective application. *c14 and r11 form an optional lowpass network to filter out potential noise from the external plvlset control source. alarm operation the alarm alm output remains in a logic-high state while det_vin is above the 1.35v nominal. alm_thres has 135k i input resistance and is set internally to 1.35v (typ) such that alm triggers when det_vin is below 1.35v. alternatively, the voltage on alm_thres can be externally driven to allow alternative power-level trip points. when det_in is used to drive the det_vin pin through r7, the nominal value for alm logic-high is typi - cally above 1.22v at det_in. the alm comparator has typical hysteresis of 29mv. layout considerations the pin configuration of the max2090 is optimized to facilitate a very compact physical layout of the device and its associated discrete components. the exposed pad (ep) of the devices 20-pin tqfn-ep package provides a low thermal-resistance path to the die. it is important that the pcb on which the device is mounted be designed to conduct heat from the ep. in addition, provide the ep with a low inductance path to electrical ground. the ep must be soldered to a ground plane on the pcb, either directly or through an array of plated via holes. component mode of operation value size supplier description vga only closed alc c1, c5 1000pf 0402 murata c0g dielectric c2, c3 0.01 f f 0402 murata x7r dielectric c8 100nf 0603 murata x7r dielectric c9 820pf 0402 murata c0g dielectric c14* do not install 0402 c16 0.01 f f 0402 murata x7r dielectric l1 330nh 0603 coilcraft ferrite ls series 5% tolerance r1 1.78k i 0402 panasonic 1% tolerance r5 150 i 0402 panasonic 1% tolerance r7 24k i 0402 panasonic 5% tolerance r11* 0 i 0402 panasonic 1% tolerance u1 20-pin tqfn (5mm x 5mm) maxim MAX2090ETP+ maxim integrated max2090 50mhz to 1000mhz analog vga with threshold alarm circuit and error amplifier for level control
