PLUTO
Dual Mode CDMA/AMPS Baseband Interface Advance Information
DS4722 - 1.8 July 1998
The PLUTO baseband interface circuit is designed for use in dual mode CDMA/AMPS digital cellular telephones. In the telephone, Pluto provides the interface between the radio (RF & IF) components and the baseband digital signal processor. Pluto is part of a complete chipset solution for CDMA phones entitled the Planet chipset. The receive (RX) section converts the analog in-phase and quadrature (I & Q) signals into equivalent digital signals whilst the transmit (TX) circuits perform the complementary function of translating digital baseband information into the analog equivalent signals required for the modulator in the radio circuits. VHF PLLS are also included for second RXLO and TXIF generation.
