Description
This electronic component model, PM7870, belongs to the IC Chips product category. It is designed with various features to enhance wireless basestation performance. The PM7870 includes Digitial Adaptive Pre-Distortion for wideband linearization of power amplifiers, Digitial Correction for Analog Quadrature Modulation Distortion, and Digital Soft Pre-compression for efficiency management. It supports an input signal bandwidth of up to 10 MHz and a sample rate of up to 80 MHz. The PM7870 also offers programmable input data rate and a 16-bit microprocessor bus interface for adaptive control processor compensation engine. With a serial interface, it can be configured to operate using SPI or I2C for updating power and carrier values. Additionally, it has 48 general-purpose IO pins, including eight edge-triggered interrupt sources, and a standard five-signal IEEE 1149.1 JTAG test port for boundary scan board test purposes.
