The AFE840x is a mulTIchannel communicaTIons signal processor that provides analog-to-digitalconversion and digital downconversion opTImized for cellular base transceiver systems. The AFE8405 andAFE8406 both support UMTS, CDMA-1X and TD-SCDMA air-interface cellular standards.The AFE8405 provides up to 8 UMTS digital downconverter channels (DDC), 16 CDMA DDCs, or 16TD-SCDMA DDCs. The DDC channels are independent and operate simultaneously. The AFE8405 hastwo input ports: one is hardwired to an internal 14-bit analog-to-digital converter and the other is a 16-bitdigital input. Each DDC channel can be programmed to accept data from any one of the two input ports.The AFE8406 provides up to 8 UMTS digital downconverter channels (DDC), 16 CDMA DDCs, or 16TD-SCDMA DDCs. The DDC channels are independent and operate simultaneously. The AFE8406 hasfour input ports: two are hardwired to internal 14-bit analog-to-digital converters and two are 16-bit digitalinputs. Each DDC channel can be programmed to accept data from any one of the four input ports.
