The TLFD600PAP is a high-speed, programmable, analog front end for customer premise equipment (CPE) modems that supports G.lite (G.992.2) and full rate (G.992.1) ADSL applications and incorporates both the codec and line drivers and receiver. The codec also coexists with home phoneline networking alliance (HPNA)-devices, with the ability to work together with up to three HPNA devices connected to the same line. The device performs transmit encoding (D/A conversion), receive decoding (A/D conversion), transmit and receive filtering functions, receive equalizer, and programmable gain amplifications (PGA). The device also incorporates a voltage compensated crystal oscillator (VCXO) DAC, DPLL, line driver, and receiver for TX and RX channels which reduces the number of system components. Two auxiliary amplifiers are provided, on-chip, for additional onboard filtering and amplification with additional off-chip passive components. The receive channel has an update rate of 1.104 Msps in the G.lite mode and 2.208 Msps in the full rate mode. The transmit channel has an update rate of 276 Ksps and 552 Ksps.
A simple serial interface on the digital side reduces system component count. Both data and control share the same serial port. The interface can connect directly to the TI C6000 and C5000 families of DSP chips.
The device operates using 3.3-V and 12-V supply lines (12 V is used for the on-chip TX line driver) and is packaged in a single 64-pin PAP (PowerPAD™) package. It is characterized for operation from 40°C to 85°C.

† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The analog input pins (RXINP/RXINM) are virtual ac ground in the normal application mode.
