DELAY BETWEEN INPUT SIGNAL (LI1 OR LI2) AND OUTPUT SIGNAL (LCR) AT 8KHz AFTER

SYNCHRONIZING (when SLCR = 1, LP4R Register Bit)

LP4

Loopback 4

When this bit is at ”1”, loop back 4 is

validated during Time Slot selected. The

loop back is located between DOUT and

DIN pins. The loop back is transparent

during the Time Slot selected. DOUT

always delivers the contents of each Time

Slot.

SLCR Synchronization of Low Clock Received

Relevant if LTM (CR1) = 0.

SLCR = 1, LCR output signal will be syn-

chronized once when MFR bit (or MFNR

bit) will go to ”1”. After synchronizing, the

falling edge of LCR signal is in accord-

ance with the 6th bit of time slot 1 seen

at the input of the circuit. (LI1 pin or LI2

pin). The input signal is assumed without

jitter.

SLCR = 0, LCR output signal is free. The

LCR frequency is a submultiple of HCR

frequency.
