1 / 32 page BIPOLAR ANALOG INTEGRATED CIRCUIT µPC8002 The µPC8002 is a monolithic IC developed for use in digital cordless telephones. Its internal equivalent circuits comprise a double balanced mixer (DBM), IF amplifier circuit, and RSSI (Received Signal Strength Indicator) circuit. The µPC8002 can operate on a wide range of power supply voltages from 2.7 V to 5.5 V, and incorporates a power- off function, making it ideal for achieving low set power consumption. The package is a 20-pin plastic shrink SOP (225 mil) suitable for high-density surface mounting. FEATURES • Low-voltage, low-consumption-current operation possible (VCC = 2.7 to 5.5 V, ICC = 3.4 mA at VCC = 3 V) • Wide mixer input frequency range (fMIX = 250 MHz (TYP.) to 500 MHz (MAX.)) • Wide IF amplifier input frequency range (fIF = 8 MHz (MIN.) to 12 MHz (MAX.), 10.7 MHz (TYP.)) • High limiting sensitivity (SL = –100 dBm (TYP.)) • Wide RSSI dynamic range (DR = 85 dB (TYP.)) • On-chip power-off function • Use of 20-pin plastic shrink SOP (225 mil) allows high-density surface mounting BLOCK DIAGRAM ORDERING INFORMATION Part Number Package µPC8002GR 20-pin plastic shrink SOP (225 mil) µPC8002GR-E1 20-pin plastic shrink SOP (225 mil) Embossed carrier taping (pin 1 is tape unwinding direction) µPC8002GR-E2 20-pin plastic shrink SOP (225 mil) Embossed carrier taping (pin 1 is tape winding direction) BYPASS1 20 IF2 OUT 11 IF1 IN 19 BYPASS2 18 IF1 OUT 17 BYPASS4 16 IF2 IN 15 BYPASS3 14 GND (IF OUT) 13 VCC (IF OUT) 12 1 10 23456789 PD RSSI OUT MIX OUT VCC (IF) VCC (MIX) LO IN GND(IF) GND(MIX) MIX IN2 MIX IN1 IF Amp 1 Power ON/OFF RSSI 2nd MIXER RSSI IF Amp 2 Output Stage SECOND MIXER + IF AMPLIFIER FOR DIGITAL CORDLESS TELEPHONES Document No. S10717EJ2V0DS00 (2nd edition) Date Published March 1997 N Printed in Japan The information in this document is subject to change without notice. © 1997 DATA SHEET |
