Texas Instruments AFE1205E/1K

Description
The AFE1205 Analog Front End from Burr-Brown is designed for single pair HDSL (High bit rate Digital Subscriber Line) systems. It provides all the active analog circuitry needed to connect an HDSL digital signal processor to an external compromise hybrid and an HDSL line transformer. The transmit and receive filter responses automatically change with clock frequency, allowing the AFE1205 to operate over a wide range of data rates. The power dissipation of the device can be reduced under digital control for operation at lower speeds. The AFE1205 will operate at bit rates from 160kbps to 2.3Mbps. It meets ETSI PSD specifications for single pair E1, as well as ETSI and ANSI PSD specifications for two pair E1 and T1.
