2000 apr 18 5 philips semiconductors preliminary speci?cation low-cost stereo ?lter dac UDA1330ATS functional description system clock the UDA1330ATS operates in slave mode only. therefore, in all applications the system devices must provide the system clock. the system frequency (f sys ) is selectable and depends on the application mode. the options are: 256f s , 384f s and 512f s for the l3 mode and 256f s or 384f s for the static pin mode. the system clock must be locked in frequency to the digital interface input signals. the UDA1330ATS supports sampling frequencies from 16 to 55 khz. application modes the application mode can be set with the three-level pin appsel (see table 1): l3 mode static pin mode with f sys = 384f s static pin mode with f sys = 256f s . table 1 selecting application mode and system clock frequency via pin appsel the function of an application input pin (active high) depends on the application mode (see table 2). table 2 functions of application input pins for example, in the static pin mode the output signal can be soft muted by setting pin appl0 to high. de-emphasis can be switched on for 44.1 khz by setting pin appl1 to high; setting pin appl1 to low will disable de-emphasis. in the l3 mode, pin appl0 must be set to low. it should be noted that when the l3 mode is used, an initialization must be performed when the ic is powered-up. multiple format input interface d ata formats the digital interface of the UDA1330ATS supports multiple format inputs (see fig.3). left and right data-channel words are time multiplexed. the ws signal must have a 50% duty factor for all lsb-justified formats. the bck clock can be up to 64f s , or in other words the bck frequency is 64 times the word select (ws) frequency or less: f bck 64 f ws . important : the ws edge must fall on the negative edge of the bck at all times for proper operation of the digital interface. the UDA1330ATS also accepts double speed data for double speed data monitoring purposes l3 mode this mode supports the following input formats: i 2 s-bus format with data word length of up to 20 bits msb-justified format with data word length up to 20 bits lsb-justified format with data word length of 16, 18 or 20 bits. s tatic pin mode this mode supports the following input formats: i 2 s-bus format with data word length of up to 20 bits lsb-justified format with data word length of 16, 18 or 20 bits. these four formats are selectable via the static pin codes sf0 and sf1 (see table 3). table 3 input format selection using sf0 and sf1 voltage on pin appsel mode f sys v ssd l3 mode 256f s , 384f s or 512f s 0.5v ddd static pin mode 384f s v ddd 256f s pin function l3 mode static pin mode appl0 test mute appl1 l3clock deem appl2 l3mode sf0 appl3 l3data sf1 format sf0 sf1 i 2 s-bus 0 0 lsb-justi?ed 16 bits 0 1 lsb-justi?ed 18 bits 1 0 lsb-justi?ed 20 bits 1 1
2000 apr 18 6 philips semiconductors preliminary speci?cation low-cost stereo ?lter dac UDA1330ATS interpolation ?lter (dac) the digital filter interpolates from 1f s to 128f s by cascading a recursive filter and an fir filter (see table 4). table 4 interpolation ?lter characteristics noise shaper the 3rd-order noise shaper operates at 128f s . it shifts in-band quantization noise to frequencies well above the audio band. this noise shaping technique enables high signal-to-noise ratios to be achieved. the noise shaper output is converted into an analog signal using a filter stream dac (fsdac). filter stream dac the fsdac is a semi-digital reconstruction filter that converts the 1-bit data stream of the noise shaper to an analog output voltage. the filter coefficients are implemented as current sources and are summed at virtual ground of the output operational amplifier. in this way very high signal-to-noise performance and low clock jitter sensitivity is achieved. a post-filter is not needed due to the inherent filter function of the dac. on-board amplifiers convert the fsdac output current to an output voltage signal capable of driving a line output. the output voltage of the fsdac scales linearly with the power supply voltage. pin compatibility in the l3 mode the UDA1330ATS can be used on boards that are designed for the uda1320ats. remark : it should be noted that the UDA1330ATS is designed for 5 v operation while the uda1320ats is designed for 3 v operation. this means that the UDA1330ATS can be used with the uda1320ats supply voltage range, but the uda1320ats can not be used with the 5 v supply voltage. item condition value (db) pass-band ripple 0 to 0.45f s 0.1 stop band >0.55f s - 50 dynamic range 0 to 0.45f s 108

2000 apr 18 8 philips semiconductors preliminary speci?cation low-cost stereo ?lter dac UDA1330ATS l3 interface the following system and digital sound processing features can be controlled in the l3 mode of the UDA1330ATS: system clock frequency data input format de-emphasis for 32, 44.1 and 48 khz volume soft mute. the exchange of data and control information between the microcontroller and the UDA1330ATS is accomplished through a serial interface comprising the following signals: l3data l3mode l3clock. information transfer through the microcontroller bus is organized in accordance with the l3 interface format, in which two different modes of operation can be distinguished: address mode and data transfer mode. address mode the address mode (see fig.4) is required to select a device communicating via the l3 interface and to define the destination registers for the data transfer mode. data bits 7 to 2 represent a 6-bit device address where bit 7 is the msb. the address of the UDA1330ATS is 000101 (bit 7 to bit 2). if the UDA1330ATS receives a different address, it will deselect its microcontroller interface logic. data transfer mode the selected address remains active during subsequent data transfers until the UDA1330ATS receives a new address command. the fundamental timing of data transfers (see fig.5) is essentially the same as the address mode. the maximum input clock frequency and data rate is 64f s . data transfer can only be in one direction, consisting of input to the UDA1330ATS to program sound processing and other functional features. all data transfers are by 8-bit bytes. data will be stored in the UDA1330ATS after reception of a complete byte. a multibyte transfer is illustrated in fig.6. registers the sound processing and other feature values are stored in independent registers. the first selection of the registers is achieved by the choice of data type that is transferred. this is performed in the address mode using bit 1 and bit 0 (see table 5). table 5 selection of data transfer the second selection is performed by the 2 msbs of the data byte (bit 7 and bit 6). the other bits in the data byte (bit 5 to bit 0) represent the value that is placed in the selected registers. the status settings are given in table 6 and the data settings are given in table 7. bit 1 bit 0 transfer 0 0 data (volume, de-emphasis, mute) 0 1 not used 1 0 status (system clock frequency, data input format) 1 1 not used

2000 apr 18 19 philips semiconductors preliminary speci?cation low-cost stereo ?lter dac UDA1330ATS soldering introduction to soldering surface mount packages this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). there is no soldering method that is ideal for all surface mount ic packages. wave soldering is not always suitable for surface mount ics, or for printed-circuit boards with high population densities. in these situations reflow soldering is often used. re?ow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 250 c. the top-surface temperature of the packages should preferable be kept below 230 c. wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was specifically developed. if wave soldering is used the following conditions must be observed for optimal results: use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. manual soldering fix the component by first soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c.
2000 apr 18 20 philips semiconductors preliminary speci?cation low-cost stereo ?lter dac UDA1330ATS suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . 2. these packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. 4. wave soldering is only suitable for lqfp, tqfp and qfp packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. wave soldering is only suitable for ssop and tssop packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. package soldering method wave reflow (1) bga, lfbga, sqfp, tfbga not suitable suitable hbcc, hlqfp, hsqfp, hsop, htqfp, htssop, sms not suitable (2) suitable plcc (3) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (3)(4) suitable ssop, tssop, vso not recommended (5) suitable
