1. general description the TEA5880TS stereo fm radio ic dramatically reduces the printed-circuit board area (only 100 mm 2 ) needed to integrate fm radio functionality into portable devices. this makes it invaluable for any application where space is at a premium. relying on a system host processor for radio tuning, the TEA5880TS is ideally suited for powerful devices such as pdas, notebooks, portable cd and mp3 players. 2. features n no alignments necessary n complete adjustment-free stereo decoder; no external crystal required n fully integrated mpx vco circuit n fully integrated low if selectivity and demodulation n the full integration level means no or few external components required n no external fm discriminator needed due to full integration n built-in adjacent channel interference total reduction (no 114 khz, no 190 khz) n the level of the incoming signal at which the radio must lock is software programmable n due to new tuning concept, the tuning is independent of the channel spacing n very high sensitivity due to integrated low noise rf input ampli?er n rf automatic gain control (agc) circuit n standby mode for power-down, no power switch circuitry required n 2.7 v minimum supply voltage n mpx output for rds n 3-wire bus n in combination with the host, fast, low power operation of preset mode, manual search, automatic search and automatic store are possible n host can be in sleep mode after tuning; a minute retuning is recommended to compensate for temperature and voltage ?uctuations n covers all japanese, european and us bands.

(1) width of printed-circuit board trace = 0.15 mm; spacing between printed-circuit board trace = 0.15 mm.

9397 750 13022 ? koninklijke philips electronics n.v. 2004. all rights reserved. preliminary data sheet rev. 02 26 april 2004 23 of 27 philips semiconductors TEA5880TS integrated fm stereo radio ic for host processor tuning 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 ?xed 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 of the leads in the wave ranges from 3 to 4 seconds at 250 c or 265 c, depending on solder material applied, snpb or pb-free respectively. a mildly-activated ?ux will eliminate the need for removal of corrosive residues in most applications. 17.4 manual soldering fix the component by ?rst soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the ?at 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. 17.5 package related soldering information [1] for more detailed information on the bga packages refer to the (lf)bga application note (an01026); order a copy from your philips semiconductors sales of?ce. [2] 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 . [3] these transparent plastic packages are extremely sensitive to re?ow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared re?ow soldering with peak temperature exceeding 217 c 10 c measured in the atmosphere of the re?ow oven. the package body peak temperature must be kept as low as possible. table 22: suitability of surface mount ic packages for wave and re?ow soldering methods package [1] soldering method wave re?ow [2] bga, htsson..t [3] , lbga, lfbga, sqfp, ssop..t [3] , tfbga, uson, vfbga not suitable suitable dhvqfn, hbcc, hbga, hlqfp, hso, hsop, hsqfp, hsson, htqfp, htssop, hvqfn, hvson, sms not suitable [4] suitable plcc [5] , so, soj suitable suitable lqfp, qfp, tqfp not recommended [5] [6] suitable ssop, tssop, vso, vssop not recommended [7] suitable cwqccn..l [8] , pmfp [9] , wqccn..l [8] not suitable not suitable

[5] 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. [6] wave soldering is suitable for lqfp, qfp and tqfp packages with a pitch (e) larger than 0.8 mm; it is de?nitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. [7] wave soldering is suitable for ssop, tssop, vso and vsop packages with a pitch (e) equal to or larger than 0.65 mm; it is de?nitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. [8] image sensor packages in principle should not be soldered. they are mounted in sockets or delivered pre-mounted on ?ex foil. however, the image sensor package can be mounted by the client on a ?ex foil by using a hot bar soldering process. the appropriate soldering pro?le can be provided on request. [9] hot bar soldering or manual soldering is suitable for pmfp packages.
