SL6619 Direct Conversion FSK Data Receiver Preliminary Information Supersedes July 1996 version, DS3853 - 3.5 DS3853 - 4.1 April 1998 The SL6619 is an advanced Direct Conversion FSK Data Receiver for operation up to 450 MHz. The device integrates all functions to convert a binary FSK modulated RF signal into a demodulated data stream. Adjacent channel rejection is provided using tuneable gyrator filters. RF and audio AGC functions assist operation when large interfering signals are present and an automatic frequency control (AFC) function is provided to extend centre frequency acceptance. 32 31 30 29 28 27 26 25 FEATURES s Very Low Power Operation from Single Cell s Superior Sensitivity s Operation at 512, 1200 and 2400 Baud s On Chip 1 Volt Regulator s 1mm Height Miniature Package s Automatic Frequency Control Function s Programmable Post Detection Filter s AGC Detection Circuitry s Power Down Function s Battery Strength Indicator APPLICATIONS s Pagers, including Credit Card, PCMCIA and Watch Pagers s Low Data Rate Receivers, e.g. Security Systems ORDERING INFORMATION SL6619/KG/TP1N SL6619/KG/TP1Q 1mm TQFP device, baked and dry packed, supplied in trays 1mm TQFP device, baked and dry packed, supplied in tape and reel IRF GND MIXIP A MIX DEC MIXIP B REG CNT VREG TPI GTH ADJ TC ADJ IAGC OP TP LIM I VBATT BRF1 BRF CNT AFC2 1 2 3 4 5 6 7 8 SL6619 24 23 22 21 20 19 18 17 AFC1 BATT FLAG VCC2 DATA OP BEC AFC OP VREF TPQ 9 10 11 12 13 14 15 16 I1 I2 VCC1 LOIP I GYR I LOIP Q Q1 Q2 TP32 Fig. 1 Pin identification diagram (top view).
