Bias. See Figure 11 for the recommended bias circuit.
SONET/SDH Clock Enable (CMOS Input). If tied high this control pin enables
the OC-CLKoP/N differential driver. Pulling this input low disables the output
clock without deactivating differential drivers.
C77 Clock Output Enable A (CMOS Input). If tied high this control pin
enables the C77oP/N-A output clock. Pulling this input low disables the output
clock without deactivating differential drivers.
C77 Clock Output Enable B (CMOS Input). If tied high this control pin
enables the C77oP/N-B output clock. Pulling this input low disables the output
clock without deactivating differential drivers.
C77 Clock Output Enable C (CMOS Input). If tied high this control pin
enables the C77oP/N-C output clock. Pulling this input low disables the output
clock without deactivating differential drivers.
C77 Clock Output Enable D (CMOS Input). If tied high this control pin
enables the C77oP/N-D output clock. Pulling this input low disables the output
clock without deactivating differential drivers.

Positive Digital Power Supply. +3.3 V ±10%
Internal Connection. Connect this pin to Ground (GND).
Frequency Select 2-1 (CMOS Input). These inputs program the clock
frequency on the OC-CLKo output. The possible output frequencies are
19.44 MHz (00), 38.88 MHz (01), 77.76 MHz (10), 155.52 MHz (11).
C19o Output Enable (CMOS Input). If tied high this control pin enables the
C19o output clock. Pulling this pin low forces output driver into a high
impedance state.
Ground. 0 volt
C19 Reference Input (CMOS Input). This pin is a single-ended input reference
source used for synchronization. This pin accepts 19.44 MHz.
Positive Digital Power Supply. +3.3 V ±10%
Ground. 0 volt
No internal bonding Connection. Leave unconnected.
