8 / 12 page Integrated L1-Band GPS Receiver 8 _______________________________________________________________________________________ Detailed Register Definitions Table 4. Detailed Register Definition for Write Address 0100: SYNTH DATA BIT DEFAULT DESCRIPTION D15 1 Reserved D14 1 LPF Autotune Initiate: I = Initiate autotune, 0 = Manual tuning. D13–D10 0100 LPF Tuning Word: 0000 ~ 7.7MHz, 1111 ~ 2.9MHz. D9 1 XTAL Clock Select: 1 = External reference, 0 = Synthesized 16.8MHz. D8 0 Standby: 0 = Normal operating mode, 1 = Standby (oscillator remains active), but only if D9 = 1. D7–D0 01100000 Reference Division Ratio. Default 19.2MHz external reference (R = 96dec). R = fREF / 200kHz. Table 5. Detailed Register Definition for Write Address 0101: CONFIG 1 DATA BIT DEFAULT DESCRIPTION D15 1 ADC Mode. Select 1 for 1-bit magnitude and sign, select 0 for 2-bit magnitude and sign. 1: GPSIF2 = sign, GPSIF1 = magnitude, GPSIF0 = X 0: GPSIF2 = MSB magnitude, GPSIF1 = LSB magnitude, GPSIF0 = sign D14–D11 0000 ADC Offset Control (approx 4mV/step): D14 = LSB, D12 = MSB, D11 = sign. D10 0 Double Charge-Pump Current: 0 = 100µA, 1 = 200µA. D9 to D8 00 Digital Test Bus Mode Select. See Table 9 for test-mode descriptions. D7 to D5 001 VCO Coarse Tuning Range. 000 = Lowest frequency, 111 = Highest frequency. D4–D0 11111 AGC Gain. Digital control of the AGC amplifier in the 2nd IF section. 00000 => min gain, 11111 => max gain (linear gain ~2.5dB per unit SPI word). Table 6. Detailed Register Definition for Write Address 0110: CONFIG 2 DATA BIT DEFAULT DESCRIPTION D15 1 Reset CMOS: 0 = Hold CMOS dividers in reset and PFD is tri-stated, 1 = Inactive. D14 1 Drive VCO Low: 0 = Active, forces VCO to lowest frequency. N.B. do not activate both D14 and D13 at the same time. D13 1 Drive VCO High: <forces LCP low FET on, driving VTUNE low, forcing VCO to highest extreme> 0 = Active, forces VCO to highest frequency. N.B. do not activate both D14 and D13 at the same time. D12–D7 100000 Reserved D6 to D5 11 Must be programmed to 11 D4–D0 11111 Analog Test Mode Select: Reserved |
