Philips UAA3545
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). The reference divider ratio is programmable to 4, 8, 12 or 16.| Part No. | UAA3545 |

ORDERING INFORMATION TYPE NUMBER UAA3545HL PACKAGE NAME LQFP32DESCRIPTION
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 is programmed via a 3-wire serial bus. Outputs of the main and reference dividers drive a phase comparator where a charge pump produces phase error current pulses for integration in an external loop filter (only a passive loop filter is necessary).
