3 V DUAL DOWNCONVERTER AND PLL FREQUENCY SYNTHESIZER UPB1007K FEATURES DESCRIPTION • INTEGRATED RF BLOCK: LNA, RF & IF Downconverter + PLL frequency synthesizer + on-chip crystal oscillator • STATE OF THE ART 25 GHz fT UHS0 BIPOLAR PROCESS • DOUBLE-CONVERSION: f1stIF = 61.380 MHz f2ndIF = 4.092 MHz NEC's UPB1007K is a Silicon RFIC designed for low cost GPS receivers. The IC combines an LNA, followed by a doubleconversion RF/IF downconverter block and a PLL frequency synthesizer on one chip. The chip also includes an on-board crystal oscillator working up to 16 MHz which can be used as a CPU reference for fast locking. The device operates on a 3 V supply voltage and is housed in a small 36 pin QFN (Quad Flat No-lead) package, resulting in low power consumption and reduced board space. The device is manufactured using the state of the art UHS0 25 GHz fT silicon bipolar process. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance. • ADJUSTABLE GAIN: 20 dB range MIN • FIXED DIVISION PRESCALER • LOW POWER CONSUMPTION: 25 mA @ 3 V • SMALL 36 PIN QFN PACKAGE Flat lead style for better performance APPLICATIONS • TAPE AND REEL PACKAGING AVAILABLE • LOW POWER HANDHELD GPS RECEIVER • IN-VEHICLE NAVIGATION SYSTEMS • PC/PDA+GPS INTEGRATION ELECTRICAL CHARACTERISTICS (TA = 25°C, VCC = 3.0 V, unless otherwise specified) SYMBOLS PART NUMBER PACKAGE OUTLINE PARAMETERS AND CONDITIONS ICC Total Circuit Current, No Signals VCC Supply Voltage UNITS MIN UPB1007K QFN-36 TYP 25 31 2.7 3.0 3.3 mA V MAX LNA (fRFin = 1575.42 MHz, ZL = ZS = 50 Ω) ZLNAin RF Input Impedance of LNA Ω 28 - j38 ZLNAop RF Output Impedance of LNA Ω 85 - jx6 P1dBLNA 1 dB Compression, Input matched dBm -22 PGLNA Power Gain LNA, Input matched, PRFin = -60 dBm dB 14 15 NFLNA Noise Figure of LNA, Input matched dB 2.8 Mixer (fRFin = 1575.42 MHz, f1stLOin = 1636.80 MHz, PLO = -10 dBm, f1stIF = 61.38 MHz, ZL = ZS = 50 Ω) ZMIXin RF Input Impedance of Mixer Ω 31 -j103 P1dBMIX 1 dB Compression (refer to input), Input matched dBm -25 PCGMIX Power Conversion Gain dB 21 NFMIX Noise Figure of Mixer (SSB), Input matched dB 9.5 ALO-IF LO Leakage to IF Pins, PLO = -10 dBm dBm -40 ALO-RF LO Leakage to RF Input Pins, PLO = -10 dBm dBm -48 ZMIXout RF Output Impedance of Mixer +152 - j9 PLL ICPOH PLL Charge Pump High Side Current @ VCPout = VCC/2 mA 1 ICPOL PLL Charge Pump Low Side Current @ VCPout = VCC/2 mA -1 fPD Phase Comparison Frequency MHz 8.184 IF Downconverter Block (f1stIFin = 61.38 MHz, f2ndLOin = 65.472 MHz, f2ndIF output = 4.092 MHz, ZS = 2kΩ, ZL = 2 kΩ) NF2ndMIX Noise Figure of 2nd IF Mixer (SSB), (ZS = 50Ω) dB 12 GV2ndMIX Voltage Gain of 2nd Mixer/Amplifier, P1stIF = -50 dBm dB 47 VGC Gain Control Voltage (Voltage at maximum gain) V 0.5 DGC Gain Control Range, P1stIF = -50 dBm dB 20 (Voltage at maximum gain) A2ndLO1stIF 2nd LO Isolation to 1st IF Input Pins, VAGC = 0 V dB -70 A2ndLO2ndIF 2nd LO Isolation to 2nd IF Output Pins, VAGC = 0 V dB -70 3.2 10 California Eastern Laboratories UPB1007K ELECTRICAL CHARACTERISTICS (TA = 25°C, VCC = 3 V, unless otherwise specified) PART NUMBER PACKAGE OUTLINE SYMBOLS UPB1007K QFN-36 PARAMETERS AND CONDITIONS UNITS MIN TYP MAX Ω) 2nd IF Amplifier Block (f2ndIF = 4.096 MHz, ZS = 2kΩ, ZL = 2 kΩ) GVLIM fBB Voltage Gain of Limiter Amplifier, PIN = -60 dBm Roll-off Frequency dB 48 MHz 110 Crystal Oscillator/Reference Amplifier Block Reference Input Minimum Level Reference Output Swing (open collector output), CL = 2 pF//RL = 10 kΩ Power Down Control Pins VREFin VREFout VIH VIL Digital Control Input High Digital Control Input Low ABSOLUTE MAXIMUM RATINGS1,2 (TA = 25°C) SYMBOLS VCC PT PARAMETERS Supply Voltage Total Power Dissipation3 UNITS RATINGS V 3.6 mW 433 TOP Operating Temperature °C -40 to +85 TSTG Storage Temperature °C -55 to +150 Notes: 1.
