DescriptionThe GC5018 is a multi-channel communications signal processor that provides digital downconversion optimized for cellular base transceiver systems. The device supports UMTS, CDMA-1X and TD-SCDMAair interface cellular standards.
The GC5018 provides up to 8 UMTS digital downconverter channels (DDC), 16 CDMA DDCs or 16 TD-SCDMA DDCs. The DDC channels are independent and operate simultaneously.
The GC5018 has four 16-bit inputs. Each DDC channel can be programmed to accept data from any one (or two for complex input mode) of the four input ports.
