Description

The AFE8406 is a multi-channel communications signal processor that provides analog to digital conversion and digital downconversion optimized for cellular base transceiver systems. The device supports UMTS, CDMA-1X and TD-SCDMA air interface cellular standards.

The AFE8406 provides up to 8 UMTS digital downconverter channels (DDC), 16 CDMA DDCs or 16 TDSCDMA DDCs. The DDC channels are independent and operate simultaneously.

At the AFE8406 inputs, there are four input ports; two are hardwired to internal 14-bit analog-to-digital converters and two are 16-bit digital inputs. Each DDC channel can be programmed to accept data from any one of the four input ports.
