This output pin toggles "High" if a Loss of Lock Condition is detected. LOL
(Loss of Lock) condition occurs if the recovered clock frequency deviates from
the Reference Clock frequency (available at either E3CLK or DS3CLK or STS-
1CLK input pins) by more than 0.5%.

RXA
****
External Resistor of 3.01K
± 1%.
Should be connected between RxA and RxB for internal bias.

RXB
****
External Resistor of 3.01K
±1%.
Should be connected between RxA and RxB for internal bias.

In-Circuit Test Input:
Setting this pin "Low" causes all digital and analog outputs to go into a high-
impedance state to allow for in-circuit testing. For normal operation, tie this pin
"High".

:
This pin is internally pulled up.

Processor Clock Input
To operate the Microprocessor Interface, appropriate clock frequency is pro-
vided through this pin. Maximum frequency is 66 Mhz.

Write Data :
To write data into the registers, this active low signal is asserted.

Read Data:
To read data from the registers, this active low pin is asserted.

Register Reset:
Setting this input pin "Low" resets the contents of the Command Registers to
their default settings and default operating configuration

Processor Mode Select:
When this pin is tied “High”, the microprocessor is operating in synchronous
mode which means that clock must be applied to the PCLK (pin 55).
Tie this pin “Low” to select the Asynchronous mode. An internal clock is pro-
vided for the microprocessor interface.
