| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Oncore GPS Chip Mixed Mode RF and Digital Monolithic GPS Sensor The Oncore GPS Chip integrated circuit was specifically designed for low power, cost effective host-based GPS applications. Measuring only 8x8 mm, the Oncore GPS Chip monolithic GPS sensor design includes a fully integrated main VCO and a multi-mode synthesizer that significantly reduce external component count and total system cost. The Oncore GPS Chip combines Motorola's proven dual down-conversion RF architecture and a 12-channel digital correlator using a 0.25m BiCMOS Silicon Germanium process for superior on-chip interference mitigation and reduced power consumption. Oncore GPS Chip features include: * * * * * * Mixed mode GPS RF down-converter and 12-channel digital correlator Host microprocessor independent architecture Fully integrated main VCO On-chip multi-mode synthesizer and LNA 65 mW typical power consumption at 16.367 MHz reference frequency with power moding capabilities for further power reduction 8x8 mm low profile 64-pin BGA package VDDE MG2000 0.8 mm Pitch 64-pin BGA VSSE VSSE VDDE D<4> D<3> D<7> D<6> D<5> A2 IRQ B2 C2 A1 B3 A3 C4 C3 A4 C5 B4 A5 D<2> VDDI VSSI A6 B5 A7 D<1> B6 D<0> A8 B7 CSB 1PPS Level Translators B8 C7 12 Channel Correlator RWB IF STROBE RESETB B1 D2 8 Interface 8 24 32 Timer Addr D_in D_out PN Generator 1PPS Generato Amp NCO C8 C1 D1 GND GND VCC_FN VCC_LIM G1 GND_FN LIM_BYP H1 Limiter D3 VCC_XTAL LIM_BYP G2 H2 E3 E1 LIM_INPUT / Recomb Logic mix2 XTAL_C 24 XTAL_B Accumulators GND_LIM G4 H3 H4 G5 H5 F5 VCC_VCO H6 VCO_TANK H7 VCO_TANK E5 VCO_TUNE G7 GND_VCO H8 MIX1_OUT F7 VCC_MIX1 G8 GND_MIX1 F8 MIX1_INPUT E7 GND_MIX1 Programmable Divider Phase Detector Charge Pump E2 GND_XTAL MIX2_OUT / VCO LNA F3 F1 GND_CP VCC_MIX2 CP_OUT VCC_CP mix1 MIX2_INPUT GND_MIX2 F2 D6 F6 VCC_LNA E8 LNA_OUT E6 GND_LNA D7 LNA_INPUT GND_LNA Pin Connections and Functional Block Diagram Motorola GPS Products Preliminary Oncore GPS Chip Specifications Revision 1.0 10/31/00 1 V MOTOROLA SEMICONDUCTOR TECHNICAL DATA Maximum Ratings Rating Operating Ambient Temperature Range Storage Temperature Range ESD Symbol TA Tstg Value -40 to 105 -55 to 150 2K Unit o o C C V ELECTRICAL CHARACTERISTICS Microprocessor Interface & Correlator Characteristic Input High Voltage Input Low Voltage Input Leakage Current Output High Voltage Output Low Voltage Pin Capacitance Min 0.8*VDDE -0.3 -1.0 VDDE-0.2 Typ 5.0 Max VDDE+0.3 0.2*VDDE 1.0 0.2 Unit Vdc Vdc A Vdc Vdc pF Power Supply Characteristic Analog Supply Voltage 1 Min 2.7 - Typ 3.0 26.19 19.3 0.5 3.0 0.1 0.1 0.5 2.0 3.8 3.2 0.5 Max 3.6 3.6 2.0 2.2 2.0 Unit Vdc mA mA A Vdc mA mA A Vdc mA mA A Analog Supply Current (16.8 MHz) 1,2 Analog Supply Current (16.367 MHz) Analog Supply Current (Quiescent) 1,2 External Supply Voltage (VDDE) External Supply Current (16.8 MHz) External Supply Current (16.367 MHz) External Supply Current (Quiescent) Internal Supply Voltage (VDDI) Internal Supply Current (16.8 MHz) Internal Supply Current (16.367 MHz) Internal Supply Current (Quiescent) 1,2 2.7 1.8 - 1.
