The MTC20154 is the fifth generation Analog Front End (AFE) designed for DMT based ADSL (Asynchronous Digital Subscriber Line) modems compliant with ANSI T1.413 category 2 standard. It includes one 12 bit DAC and one 13 bit ADC.It isintended to be used with the MTC20156/ MTC20147 DMT/ATM processors as part of the MTK20150/MTK20141 chipsets, but may also be used to support other xDSL signal processors.
The MTC20154 provides programmable low pass filters for each of the two channels and automatic gain control. A configuration pin allows the filters to be switched from ATU-R mode to ATU-C mode. The pipeline ADC architecture provides 13 bit dynamic range and a signal bandwith of 1.1 MHz. The device consumes only 0.35 Watt in full operation and has a power down mode for standby. It is housed in a compact 64 pin thin plastic quad flat package.
