General Description

The AD6633 is a multichannel, wide bandwidth digital upconverter (DUC) with crest factor reduction (CFR) technology, which is available in 4-channel or 6-channel versions.

It processes 20-bit baseband input data and generates 18-bit, wideband, real, or complex output data at up to 125 MSPS.

This rate is suitable for driving digital-to-analog converters (DACs) at the first intermediate frequency (IF) directly.

Overview

Multichannel Digital Upconverter with VersaCREST™ Crest Reduction Engine AD6633 www.DataSheet4U.

Key Features

4 or 6 wideband digital upconverter channels VersaCREST crest reduction engine reduces demands on external power amplifiers One 20-bit complex input port (I, Q interleaved), shared among 4 or 6 processing channels Two 18-bit output ports for parallel I and Q or a single 18-bit output port for interleaved I and Q All-pass phase equalizer filters (meets IS-95 requirements) Programmable RAM coefficient FIR filters (RCF) with resampling FIR interpolating filters, 2 per channel Fifth-order interpolat.
