PRODUCT SUMMARY
CX20529: CDMA/FM/GPS Baseband Analog Processor
APPLICATIONS
* Tri-band, quad-mode mobile phones (including E911 capabilities) * GPS receivers The CX20529 is a receive-only Baseband Analog Processor (BAP) that can be used for Code Division Multiple Access (CDMA), Advanced Mobile Phone System (AMPS) Frequency Modulation (FM), and Global Positioning System (GPS) baseband signals. The device is designed for dual-mode CDMA and AMPS portable phones with GPS capability.

The CX20529 is designed to interface between the Radio Frequency (RF) receive section and the digital processing Single supply voltage 2.7 to 3.3 V circuitry of the telephone. The device includes all of the Operational temperature -30 C to +85 C circuitry needed to support the receive baseband signal Low power consumption in all operating modes including processing and conversions between analog and digital signals sleep operation for CDMA, AMPS (FM), and GPS operation. For a given Dual mode for CDMA and FM operation with GPS position operation, the CX20529 accepts analog baseband In-phase (I) location capability and Quadrature-phase (Q) signals, performs channel selection Receive signal path includes: low-pass filtering, and converts the analog baseband signals - Separate CDMA, FM, GPS filters, and A/Ds into digital signals. For clock generation, the CX20529 includes - DC offset control loop internal digital and Phase-Locked Loop (PLL) clock synthesis Receive VHF PLL synthesizer: for 19.2, 19.68, and 19.8 MHz system clocks. The device also provides the capability to generate or to accept the CHIPx8 - Programmable charge pump current .comto or from the Mobile Station Modem (MSM) or clock - Lock detector output equivalent baseband device. The CX20529 also integrates a System clock generation: VHF PLL synthesizer to synthesize the receive Intermediate - 19.2, 19.68, and 19.8 MHz system clock support Frequency (IF). - Accepts external CHIPx8 clock (9.8304 MHz or 8.184 MHz) and generates an internal The CX20529 is characterized for operation from a power CHIPx8 clock (9.8304 MHz) supply voltage range of 2.7 V to 3.4 V, with power control logic - Adjustable TCXO or TCXO/4 clock output driver levels and maintaining a minimum power consumption. Electrical power-down capability performance parameters are designed to operate over the - Provides a TCXO clock through the TCXO/4 output pin -30 C to +85 C range. The device is available in 40-pin Mode control logic for Rx, sleep, idle, and GPS modes 6 x 6 mm Land Grid Array (LGA) package. A system block Pin-for-pin and functionality compatible with the CX20489 diagram of the CX20529 is shown in Figure 1. (but with GPS processing capability added) Available in a 40-pin, 6 x 6 mm LGA package
