CX74063 - RF Transceiver

Key Features

  • an integrated, fully programmable, sigma-delta fractional-N synthesizer suitable for GPRS multi-slot operation. Except for the loop filter, the frequency synthesizer function, including a wideband VCO, is completely on-chip. The reference frequency for the synthesizer is supplied by the integrated crystal oscillator circuitry. The CX74063 is available as a 56-pin RFLGA™ 8x8 mm package. Package dimensions are shown in Figure 1. Features.
  • Direct down-conversion receiver eliminates the ex.

www.DataSheet4U.com CX74063 RF Transceiver for Multi-Band GSM/GPRS/EDGE Applications with Integrated Crystal Oscillator and Power Ramping Controller The CX74063 transceiver is a highly integrated device for multi-band Global System for Mobile Communications™ (GSM™) or General Packet Radio Service (GPRS) applications. The device requires a minimal number of external components to complete a GSM radio subsystem. The CX74063 supports GSM850, EGSM900, DCS1800, and PCS1900 applications. The receiver also supports downlink Enhanced Data-Rate GSM Evolution (EDGE). The receive path implements a direct down-conversion architecture that eliminates the need for Intermediate Frequency (IF) components.
