RF6001 Preliminary 0 FRACTIONAL-N RF SYNTHESIZER WITH MODULATOR AND DIGITAL IF FILTER Typical Applications • GSM/DCS Handsets • Multi-Band EDGERX Handsets • GSM/DCS/PCS Handsets • Multi-Band GPRS Handsets • Quad-Band GSM Handsets Product Description 5 0.10 C A -A- The RF6001 is a combination synthesizer and signal processing IC, which along with the RF2710/RF2716 VeryLow-IF Receive IC, constitutes RFMD's 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 RF2710/RF2716. 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. 0.08 C 2 PLCS 7.00 TYP 6.75 TYP 3.50 TYP 3.37 TYP 0.90 0.85 0.70 0.65 0.05 0.00 0.10 C B 2 PLCS 2 PLCS 0.10 C B 2 PLCS -B- 0.10 C A 0.30 0.18 3 0.10 M C A B NOTES: 1.
