Description
The CPC5601 is a serially-programmed driver IC for
use with Clare, Inc.
The CPC5601 allows host-
equipment control of DAA characteristics for world-
wide DAA implementations, avoiding multiple imple-
mentations with discrete component changes or “stuff”
options. The small, low-profile package makes the
CPC5601 ideal for 56K PC Card (PCMCIA) modems,
PC motherboards, and soft-modems.
The CPC5601 uses opto-electronics to maintain the
isolation barrier required in the data access arrange-
ment for connection of host devices to the public
switched telephone network (PSTN).
The one-bit serial input of the CPC5601 recovers
clocking information from the input signal to set bits in
the shift register. The shift register outputs connect to
open-drain FET latches that are used to switch in dif-
ferent external components to set V/I slope, DC termi-
nation current limit, gain, and AC termination value in
LITELINK DAA implementations.The CPC5601 does
not need a clock signal for shift register operation, but
relies on internal timing instead.
