DESCRIPTION

The GC533x is a wideband transmit and receive

signal processor that includes digital downconverter /

upconverter (DDUC), transmit, receive, and capture

buffer blocks. The transmit path includes crest factor

reduction (CFR), digital predistortion (DPD) and

associated feedback path, complex equalization, and

bulk upconversion.

•

DPD: Memory Compensation, Typical ACLR

Improvement of 20 dB or More

RX-Receive Includes DC-Offset Cancellation,

Front-End and Back-End AGC, Bulk

Downconverter, RX Equalizer, I/Q Imbalance

Correction, DDC

The receive path includes wideband and narrowband

automatic gain control (AGC), bulk downconversion,

complex equalization, and I/Q imbalance correction.

•

4 DDUCs, 1–12 Channels per DDUC, Each

DDUC Can Be Programmed to TX or RX, at a

Common Resampler Rate – Multimode

Support

The DDUC section consists of four identical DDUC

blocks, each supporting up to 12 channels. Each

channel has independent fractional resamplers and

NCOs to enable flexible carrier configurations.

Multi-mode/multi-standard

supported by configuring the individual DDUC blocks

to different filtering and oversampling scenarios.
