Preliminary
PM7800 PALADIN-10
Digital Correction Signal Processor
FEATURES
· Digitial Adaptive Pre-Distortion for wideband linearization of power amplifiers in wireless basestations. · Digitial Correction for Analog Quadrature Modulation Distortion. · Digital Soft Pre-compression for efficiency management. · Input Signal Bandwidth up to 10 MHz. Sample rate up to 80 MHz. · Programmable, variable input data rate. · 16-bit microprocessor bus interface for adaptive control processor compensation engine. · Serial interface (configurable to SPI or I2C operation) for update of power and carrier values. · 48 general-purpose IO pins, eight of which are edge-triggered interrupt sources. · Standard five-signal IEEE 1149.1 JTAG test port for boundary scan board test purposes.
APPLICATIONS
· Multi-carrier WCDMA Base Transceiver Subsystems (BTS). · CDMA2000 BTS (requires firmware upgrade). · GSM/TDMA/EDGE BTS (requires firmware upgrade).
PACKAGING
· Low-power 1.8 V CMOS core logic with 3.3 V CMOS/TTL compatible digital inputs and digital outputs. · Industrial temperature range (-40 °C to +85 °C). · 304-pin SBGA with a body size of 31mm x 31mm.
