DESCRIPTION
The GC6016 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), complex equalization, and bulk
upconversion.
The GC6016 is a related product to the GC5330, with
the DPD block not functional. The GC6016 has an
identical package and footprint with the GC5330.The
receive path includes wideband and narrowband
automatic gain control (AGC), bulk downconversion,
complex equalization, and I/Q imbalance correction.
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 operation can be
supported by configuring the individual DDUC blocks
to different filtering and oversampling scenarios.
