* Pin order follows symbol order, e.g., pin 170 refers to TLSDATA7I.
I = input, O = output, I/O = bidirectional signal, I
d
= input with internal pull-down (~20 kW), I

or
O
diff
= differential input or output. All I/O not explicitly stated with a buffer type are 5 V compatible. They will tolerate 5 V at their inputs or out-
puts. LVDS = low-voltage differential signal.

serial mode, then this output is used as the differential data pin. In
nibble or parallel output mode, this output is placed in a high-
impedance state.
O
Transmit High-Speed Clock.
The STS-3/STM-1 (AU-4) clock is
38.88 MHz for nibble data, or 19.44 MHz for byte-wide data.
O
Transmit High-Speed Sync
. The STS-3/STM-1 (AU-4) 8 kHz frame
sync is coincident with the first or last nibble/byte of the frame.
O
Transmit High-Speed Data.
Bit 7 is the most significant bit in nibble
or byte mode.
O
Transmit High-Speed Parity.
The parity output is only defined for
nibble or byte-wide data. The device can be provisioned to source
either an odd or even parity bit.
