| NEC's LOW POWER GPS RF RECEIVER BIPOLAR ANALOG + INTEGRATED CIRCUIT UPB1009K DESCRIPTION The PB1009K is a silicon monolithic IC developed for GPS receivers. This IC integrates a full VCO, second IF filter, 4-bit ADC, and digital control interface to reduce cost and mounting space. In addition, its power consumption is low. Moreover, use of a TCXO with frequency of 16.368 MHz/16.384 MHz, 14.4 MHz, 19.2 MHz, or 26 MHz switchable with an on-chip divider is possible. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance.

TYP. MAX. Unit 10 kHz - -30 Remarks 1. Timing characteristics of ADC during normal operation A buffer amplifier is internally inserted before the ADC core of the PB1009K. The bias of this buffer amplifier is controlled by the signal input from the DC trim pin, and is used to eliminate the DC offset of the ADC. Because the ladder resistor of the ADC is directly connected between VDDana and GNDana, changes in VDDana affect the resolution of the ADC. 14 UPB1009K As illustrated in the operation timing chart below, the data of SampleN is pipeline delayed by 1.5 clocks during normal operation, and is output at the rising edge of the sample clock with output delay time Tod. When the operation is changed from normal operation to power-down operation, the status of the output data immediately before the power-down operation is retained (drive status). The following table shows each timing parameter for reference purposes.

Power-down timing characteristics of ADC The output code of the ADC of the PB1009K is undefined for 7.5 clocks after the power-down signal is cleared when the ADC returns from the power-down status to normal operation. N o t e The output data is undefined from the start of the power-down operation to the 7.5th clock from the falling edge of the clock at which the power-down operation is cleared. 16 UPB1009K TYPICAL CHARACTERISTICS (TA = +25C, VCC = 3.0 V, unless otherwise specified) IC TOTAL CHARACTERISTICS Remark The graphs indicate nominal characteristics. 17 UPB1009K PRE-AMPLIFIER BLOCK CHARACTERISTICS Remark The graphs indicate nominal characteristics. 18 UPB1009K RF MIX BLOCK CHARACTERISTICS Remark The graphs indicate nominal characteristics. 19 UPB1009K IF BLOCK CHARACTERISTICS Remark The graphs indicate nominal characteristics. 20 UPB1009K VCO MODULATION SENSITIVITY CHARACTERISTICS C/N CHARACTERISTICS Remark The graphs indicate nominal characteristics. 21 UPB1009K SINAD MHz) CHARACTERISTICS OF A/D CONVERTOR (IFin = 5.17 MHz, SCLKin = 20.48 Remark The graphs indicate nominal characteristics. 22 UPB1009K MEASUREMENT CIRCUIT 23 UPB1009K DESCRIPTION Pin No. 1 2 3 4 5 6 7 OF PINS OF TEST CIRCUIT Pin No. 14 15 16 17 18 19 20 Sampling Signal Input AGC Input Pin Function DC Offset Input Digital Signal Output Pin Pin Name DCOFFin D0 D1 D2 D3 SCKin AGCin Pin Function Preamplifier Input Preamplifier Output RF Mixer Input MS1 Prescaler Input VCO Power Control Pin Pin Name PreAmpin PreAmpout 1stMIXin MS1 Presin VCOc VT Measurement Pin (Charge Pump CPout Output) MS2 Reference Clock Input Clock Output 2ndIF Output 2ndIF Input DC Offset Output MS2 REFin CLKout 2ndIFout 2ndIFin DCOFFout 8 9 10 11 12 13 21 22 23 24 25 AGC Control Voltage Output PD1 Output (Default onboard : GND) PD1 Output (Default on board : VCC) 1stIF Input 1stIF Output AGCout PD1 PD2 1stIFin 1stIFout 24 UPB1009K APPLICATION CIRCUIT PD1 0 1 1 0 PD2 0 0 1 1 Power-down mode Sleep mode (full off) Warm-up mode (PLL on) Calibration mode (PLL on) Active mode (full on) MS1 0 0 1 1 MS2 0 1 0 1 TCXO 16.368/16.384 MHz 19.2 MHz 14.4 MHz 26.0 MHz N 100 256/3 1024/9 4096/65 25 UPB1009K PACKAGE 44-PIN DIMENSIONS QFN (UNIT: mm) PLASTIC Caution The island pins located on the corners are needed to fabricate products in our plant, but do not serve any other function. Consequently the island pins should not be soldered and should remain non-connection pins. 26 UPB1009K NOTES ON CORRECT USE (1) Observe precautions for handling because of electro-static sensitive devices. (2) Form a ground pattern as widely as possible to minimize ground impedance (to prevent abnormal oscillation). (3) Keep the wiring length of the ground pins as short as possible. (4) Connect a bypass capacitor to the VCC pin. (5) High-frequency signal I/O pins must be coupled with the external circuit using a coupling capacitor.
