lows to get a T1.413Issue 2 compliantsolution.
The STLC60134S analog front end handles 2
transmission channelson a balanced 2 wire inter-
connection; a 16 to 640Kbit/s upstream channel
and a 1.536 to 8.192Mbit/sdownstreamchannel.
A 256 carrier DMT coding (frequency spacing
4.3125kHz) transforms the downstream channel
to a 1MHz bandwidth analog signal (tones 32-
255) and the upstream channel (tones 8-31) to a
100kHz bandwidthsignal on the line.
This asymmetrical data transmissionsystem uses
high resolution, high speed analog to digital and
digital to analog conversion and high order ana-
log filtering to reduce the echo and noise in both
