55
REF0
Reference (Input).
This is one of three (REF0, REF1 and REF2) input reference sources
used for synchronization. One of seven possible frequencies may be used: 2 kHz, 8 kHz,
1.544 MHz, 2.048 MHz, 8.192 MHz, 16.384 MHz or 19.44 MHz. This pin is internally
pulled down to GND.
56
REF_SYNC0
REF Synchronization Frame Pulse 0 (Input).
This is the 2 kHz or 8 kHz (multi) frame
pulse synchronization input associated with the REF0 reference. While the PLL is locked
to the REF0 input reference the output (multi) frame pulses are synchronized to this
input. This pin is internally pulled down to GND.
57
REF1
Reference (Input).
See REF0 pin description.
58
REF_SYNC1
REF Synchronization Frame Pulse 1 (Input).
This is the 2 kHz or 8 kHz (multi) frame
pulse synchronization input associated with the REF1 reference. While the PLL is locked
to the REF1 input reference the output (multi) frame pulses are synchronized to this
input. This pin is internally pulled down to GND.
59
REF2
Reference (Input).
See REF0 pin description.
60
APP_SEL0
Application Selection (Input).
See APP_SEL1 pin description.
61

No internal bonding Connection.
Leave unconnected.
62
63
TIE_CLR
TIE Circuit Reset (Input).
A logic low at this input resets the Time Interval Error (TIE)
correction circuit resulting in a realignment of input phase with output phase.
64
BW_SEL
Filter Bandwidth Selection (Input).
This pin selects the bandwidth of the DPLL loop
filter, see Table 2 on page 20.
