GENERAL DESCRIPTION
The UAA2080 is a high-performance low-power radio receiver circuit primarily intended for VHF, UHF and 900 MHz pager receivers for wide area digital paging systems, employing direct FM non-return-to-zero (NRZ) frequency shift keying (FSK).
The receiver design is based on the direct conversion principle where the input signal is mixed directly down to the baseband by a local oscillator on the signal frequency. Two complete signal paths with signals of 90° phase difference are required to demodulate the signal. All channel selectivity is provided by the built-in IF filters. The circuit makes extensive use of on-chip capacitors to minimize the number of external components.
The UAA2080 was designed to operate together with the PCA5000A, PCF5001 or PCD5003 POCSAG decoders, which contain a digital input filter for optimum call success rate.

Table 1 Tolerances of components shown in Figs 1 and 2 (notes 1 and 2)
Notes
1. Recommended crystal: f
XTAL
= 57.647 MHz (crystal with 8 pF load), 3rd overtone, pullability >2.75 × 10−6/pF (change in frequency between series resonance and resonance with 8 pF series capacitor at 25 °C), dynamic resistance R1 < 40 , f=±5×10−6 for T
amb
= 10 to +55 °C with 25 °C reference, calibration plus aging tolerance:
5 × 106to +15 × 10−6.
2. This crystal recommendation is based on economic aspects and practical experience. Normally the spreads for R1, pullability and calibration do not show their worst case limits simultaneously in one crystal. In such a rare event, the tuning range will be reduced to an insufficient level.
