THEORY OF OPERATION
CS61577 Enhancements Relative to CS61574
Existing designs using the CS61574 can be con-
verted to the higher performance, pin-compatible
CS61577 with no changes to the PCB, external
component or system software.
The CS61577 provides higher performance and

transmitter short-circuit current
limiting for E1 (per OFTEL OTR-001),
internally controlled pulse width for E1
output options,
35% lower power consumption,
Increased transmitter immunity to signal re-
flections for improved signal quality,
Optional AMI, B8ZS, HDB3 encoder/de-
coder or external line coding support,
Receiver AIS (unframed all ones) detection,
Improved receiver Loss of Signal handling
(LOS set at power-up, reset upon receipt of
3 ones in 32 bit periods with no more than
15 consecutive zeros),
Transmitter TTIP and TRING outputs are
forced low when TCLK is static,
The Driver Performance Monitor operates
over a wider range of input signal levels.
Introduction to Operating Modes
The CS61577 supports three operating modes
which are selected by the level of the MODE pin
as shown in Tables 1 and 2, Figure 7, and Figures
A1-A3 of the Applications section.
The modes are Hardware Mode, Extended Hard-
ware Mode, and Host Mode. In Hardware and
Extended Hardware Modes, discrete pins are used
to configure and monitor the device. The Ex-
tended Hardware Mode provides a parallel chip
select input which latches the control inputs al-
lowing individual ICs to be configured using a
common set of control lines. In the Host Mode,
an external processor monitors and configures the
device through a serial interface. There are thir-
teen multi-function pins whose functionality is
determined by the operating mode. (see Table 2).
