Note:
1. The Transmitter Latency is defined as the delay time from when a valid data word at TX[00:19] is clocked into the transmitter
(triggered by the rising edge of TBC during the time th) and when the first serial bit is transmitted on pins ± SO (defined by the
leading edge of the first bit transmitted).

Note:
1. The Receiver Latency is defined as the delay time from receiving the first serial bit of a parallel data word (defined by the rising
edge of the first bit received at pins ± DI), and when that word is first clocked out at RX[00:19] (as defined by the falling edge of
RBC0 or RBC1, following time ts).

C
Input TTL. Floats high when left open.
Output TTL.
50 Ω buffer line logic output driver. Should be ac coupled to drive 50 Ω loads. It can also
drive the I-H50 inputs through differential direct coupling. Note: all unused outputs should
be terminated with 50 Ω to VCC.
Input with internal 50 Ω terminations. Input is diode level shifted so that it can swing around
VCC. Can be driven with single-ended or differential, ac coupled configuration. To avoid
permanent damage, these inputs should not be connected to ground.
External circuit node.
S
Power supply or ground.
