The RF6001 is a combination synthesizer and signal pro-
cessing IC, which along with the RF2710/RF2716 Very-
Low-IF Receive IC, constitutes RFMD's low-cost GSM
transceiver solution. The high-performance fractional-N
synthesizer offers numerous features including a fully dig-
ital 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 RF2710/RF2716. The
IF inputs are digitized, filtered and downconverted to
baseband I and Q signals. The flexible baseband inter-
face can be configured for either analog or digital opera-
tion. Chip functionality is controlled through a three-wire
serial data interface (SDI) bus.
