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