GC5325 Description
The GC5325 is a wideband digital predistortion transmit processor that includes a crest factor reduction (CFR) block and a digital predistortion (DPD) block with its associated feedback chain and capture buffers. The GC5325 processes posite input bandwidths of up to 20 MHz and processes DPD sample rates of up to 140 MHz. The GC5325 accepts a posite signal over an interleaved parallel interface at a data rate of up...
