the RX pin and the TXIR pin.
Jitter is the possible variation of the desired edge.
Offset is the propagation delay of the input signal (RXIR
or TX) to the output signal (RX or TXIR).
The first bit on the output pin (on RX or TXIR) will show
jitter compared to the input pin (RXIR or TX), but all
remaining bits will be a constant distance.

The device can be placed in a low power mode by
disabling the device (holding the EN pin at the low
state). The internal state machine is monitoring this pin
for a low level, and once this is detected the device is
disabled and enters into a low power state.
2.8.1
When the device is disabled, the device is in a low
power state. When the EN pin is brought to a high level,
the device will return to the operating mode. The device
requires a delay of 1000 T
transmitted or received.
