Description

The CPC5601 is a serially-programmed driver IC for

use with IXYS Integrated Circuits Division’s LITELINK

CPC5601 allows host-equipment control of DAA char-

acteristics for worldwide DAA implementations, avoid-

ing multiple implementations with discrete component

changes or “stuff” options. The small, low-profile pack-

age 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.

The CPC5601 also includes an opto-coupler for ring

detection applications where the AC coupled ring

detector of the LITELINK DAA is not used.
