PRODUCT SUMMARY

CX20536: CDMA and GPS Baseband Analog Processor

analog and digital signals for CDMA and GPS operation. For a

given operation, the CX20536 accepts analog In-phase (I) and

Quadrature (Q) signals, performs channel selection low-pass

filtering, and converts the analog baseband signals into digital

Applications

• Dual-band, dual-mode mobile phones (including E911

capabilities)

• GPS receivers

signals. For clock generation, the CX20536 includes internal

digital and Phase Locked Loop (PLL) clock synthesis for 19.2,

19.68, and 19.8 MHz system clocks. It also provides the

capability to accept the CHIPx8 clock from the Mobile Station

Modem (MSM) or equivalent baseband device. The CX20536 also

integrates a VHF PLL synthesizer to synthesize a receive

Intermediate Frequency (IF) Local Oscillator (LO).

Features

• Single supply voltage 2.7 to 3.3 V

• Operational temperature –30 °C to +85 °C

• Low power consumption in all operating modes including sleep

operation

The CX20536 operates within a power supply voltage range of 2.7

V to 3.3 V. Power control logic maintains a minimum power

consumption. Electrical performance parameters are designed to

operate over the –30 °C to +85 °C range. The device is available

in a 32-pin, 5 x 5 x 1 mm RF Land Grid Array (RFLGA) package.

The device package and pinout are shown in Figure 1. A system

block diagram of the CX20536 is shown in Figure 2.

• Single mode for CDMA phones, but also with GPS position

Description

The CX20536 is a receive-only Code Division Multiple Access

(CDMA) and Global Positioning System (GPS) Baseband Analog

Processor (BAP) for dual-mode CDMA and GPS-capable portable

phones. The device is designed to interface between the receive

section and the digital processing circuitry of the telephone.
