description
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.
