Product Description
The RF6001 is a combination synthesizer and signal processing IC, which along with the RF2722 Very-Low-IF Receive IC, constitutes RFMDs low-cost GSM transceiver solution. The high-performance fractional-N synthesizer offers numerous features including a fully digital GMSK modulator with provisions for an analog I/Q interface and extremely low current consumption. The signal processor section provides a digital receive filter path designed to complement the RF2722. The IF inputs are digitized, filtered and downconverted to baseband I and Q signals. The flexible baseband interface can be configured for either analog or digital operation. Chip functionality is controlled through a three-wire serial data interface (SDI) bus. The RF2722 is part of the POLARISTM TOTAL RADIOTM solution.
