GC5330说明: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.
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.
