GENERAL DESCRIPTION
The UAA2082 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 battery monitoring circuit has an external sense input
and a 1.1 V detection threshold for easy operation in a
single-cell supply concept.
The UAA2082 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 Ω, ∆f=±5×10−6 for T
amb
= −10 to +55 °C with 25 °C reference, calibration plus aging tolerance:
−5 × 10−6to +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.
