MTC20454 General Description

The MTC20454 is the first DynaMiTe ADSL (Asynchronous Digital Subscriber Line) analog front end designed specifically for the central office. It is afifth generation Analog Front End (AFE) designed for DMT based ADSL modems compliant with ITU G.992.1 and G.992.1 standards. It includes four 12 bit DACs and one 13 bit ADC.

It is intended to be used with the MTC20455 DMT/ ATM processor as part of the MTK20450. The MTC20454 provides programmable low pass filters for each of the two channels and automatic gain control for four individual ADSL modems.

The pipeline ADC architecture provides 13 bit dynamic range and a signal bandwidth of 1.1 MHz. The device consumes only 0.7 Watt in full operation of all four modems and has a power down mode for standby.

It is housed in a compact 100 pin thin plastic quad flat package.

MTC20454 Maximum Ratings

Operation of the device beyond these limits may cause permanent damage. It is not implied that more than one of these conditions can be applied simultaneously.
