AFE8406 宽带多载波接收器

The AFE8406 is a multichannel 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 TD–SCDMA DDCs. The DDC channels are independent and operate simultaneously.

The AFE8406 DDCs have 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
