GC5016,pdf(Wideband Quad Digit

The GC5016 is a flexible wideband 4-channel digital up-converter and down-converter. The GC5016 is designed for high-speed, high bandwidth digital signal processing applications like 3G cellular base transceiver station transmit and receive channels. The GC5016 is also applicable for general-purpose digital filtering applications. The four identical processing channels can be independently configured for up-conversion, down-conversion or a combination of two up-conversion and two down-conversion channels.

In up-conversion mode, the channel accepts real or complex signals, interpolates them by programmable amounts ranging from 1 to 4096, and modulates them up to selected center frequencies. The 4 digital up-converter channels signals can be output individually, summed together on one or two outputs on a single GC5016, or optionally summed between multiple GC5016s.
