INTEGRATED CIRCUITS DATA SHEET UAA3545 Fully integrated DECT transceiver Product specification File under Integrated Circuits, IC17 2001 Sep 06 Philips Semiconductors Product specification Fully integrated DECT transceiver FEATURES Economical solution for a radio in DECT cordless telephones Integrated low phase noise VCO with no production tuning required Fully integrated receiver with high sensitivity Dedicated DECT PLL synthesizer 3 dBm output preamplifier with an integrated switch 3-line serial interface bus Low current consumption from a 3.2 V supply Compatible with Philips Semiconductors baseband chips (PCD509xx and PCD80xxx) Reduced number of control signals. APPLICATIONS DECT cordless telephones: 1880 to 1930 MHz. GENERAL DESCRIPTION The UAA3545 BiCMOS device is a low power, highly integrated circuit, for Digital Enhanced Cordless Telecommunication (DECT) applications. It features a fully integrated receiver, from antenna filter output to the demodulated data output, a fully integrated VCO, a synthesizer to implement a phase-locked loop for DECT channel frequencies and a TX preamplifier to drive the external transmit power amplifier (CGY20xx series or UAA359x series of Philips integrated circuits). ORDERING INFORMATION TYPE NUMBER UAA3545HL PACKAGE NAME LQFP32 DESCRIPTION plastic low profile quad flat package; 32 leads; body 5 × 5 × 1.4 mm UAA3545 The synthesizer’s main divider is driven by the prescaler output in the range of 1880 to 1930 MHz and...
