Part No. W682388
Datasheet
Request PDF
Description
The W682388 implements a dual channel FXS telephone line interface optimized for short loop applicati
o
dual SLCC (Subscriber Line Control Circuit) functionality with a dual channel programmable CODEC. Th
e
supports internal ringing up to 90V
PK
(5REN at 4kft) ideal for customer premise equipment (CPE). The C
O
configured for µ-law/A-law or 16-bit linear PCM encoding and supports a comprehensive set of signaling
c
required to supervise and control both telephone lines. These include tone generation, including ring ton
e
generation and detection as well as FSK and metering pulse generation. An on-chip dual pulse width mo
d
driver allows the control of DCDC conversion for each line. Programmable impedance and transhybrid b
a
for worldwide deployment.
