CPC5601 LITELINK™ Family
Auxiliary Programmable Driver IC
Description
The CPC5601 is a serially-programmed driver IC for
use with Clare, Inc. LITELINK Silicon Data Access
Arrangement (DAA) ICs. 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.
The CPC5601 also includes an opto-coupler for ring
detection applications where the AC coupled ring
detector of the LITELINK DAA is not used.

2.7 Operational Sequence
In the application circuits above, the CPC5601 is pow-
ered from the telephone line only when the LITELINK
is off-hook. This requires that you set the telephone
line characteristics controlled by the CPC5601 under
host system control immediately after taking the DAA
off-hook or after pulse dialing is complete, using the
following sequence:
1. For incoming calls, validate a ring signal by hav-
ing the host system poll or read the output of
RING (ring detect via snoop circuit on the
LITELINK) or RING (ring detect via opto-isolated
ring circuit in the CPC5601).
2. Assert OH to complete the connection.
3. Set the telephone line characteristics of the DAA
using the CPC5601 via the programming method
(see “Programming” on page 12).
With this circuit, you must program the CPC5601 as
soon as possible after asserting off hook. Leaving the
CPC5601 unprogrammed leaves open the possibility
of LITELINK instability due to lack of AC termination.
2.8 Output Current Ratings
Output b6 is the only output that can be used for the
current limiting function of a DAA. The FET on output
b6 can sink up to 120 mA of current, while the other
outputs can sink up to 10 mA.
The other outputs can be used for any of the other
switchable functions on the telephone line side of a
DAA, as long as the current does not exceed the
10 mA limit.
