3 / 76 page  1999 May 10 3 Philips Semiconductors Product specification Global Positioning System (GPS) front-end receiver circuit UAA1570HL 1 FEATURES • Complete single-chip programmable double-superheterodyne C/A-code GPS receiver • Programmable high IF frequencies supporting wideband/P-code GPS and Global Navigation Satellite System (GLONASS) applications • Supports frequency plans with a 2nd IF of 4 × f0(1.023 MHz) = 4.092 MHz • 48-pin LQFP package •−40 to +85 °C operating temperature range • 2.7 V minimum supply voltage • Low DC power consumption [57 mA typical with both Low-Noise Amplifiers (LNAs) active] • Power-down mode (<900 µA) • Typical receiver noise figure at 1.57542 GHz: 4.5 dB • Typical phase noise −72 dBc/Hz at 10 kHz offset • Simple microstrip LNA1/2 and first mixer matching • Single pin VCO with external varactor and resonator • Digital Phase Locked Loop (DPLL) synthesizer with programmable VCO, 2nd Local Oscillator (LO) and reference dividers • 3-bit synthesizer and power-down control input • Reference and independent sample clock input with internal squaring • 1-bit amplitude quantized and time sampled TTL/CMOS compatible output driver • High active gain supporting SAW filter applications • Configurable for external first LNA applications. 2 GENERAL DESCRIPTION The UAA1570HL is a complete single-chip double-superheterodyne receiver front-end intended for GPS and GLONASS navigation systems. The IC includes a programmable on-chip DPLL synthesizer, VCO with external varactor and resonator, a 1-bit amplitude quantizer and a time sampled TTL/CMOS compatible SIGN output bit driver. It can be used with either an active or passive antenna system by disabling or enabling the on-chip LNAs and is ideally suited for low power GPS receiver applications because of its 3 V supply and the power management features through control pins. Programmable prescaler controls provide the flexibility of using different frequency schemes. The UAA1570HL is optimized to provide SIGN bit data to the companion Philips part, the SAA1575HL baseband digital signal processor. The SAA1575HL can provide the sample clock input to the UAA1570HL by dividing a TTL/CMOS level reference clock signal down to a programmable sampling clock output frequency. Both ICs can also be used independently. The UAA1570HL is supplied in a low profile, 48-pin LQFP package for excellent Radio Frequency (RF) performance and small size. 3 ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION UAA1570HL LQFP48 plastic low profile quad flat package; 48 leads; body 7 × 7 × 1.4 mm SOT313-2 |
