5 Narrow timestamp encoder

The css600_ntsencoder converts the 64-bit timestamp value from the timestamp generator to a 7-bit encoded value, called a narrow timestamp.

The narrow timestamp encoder also encodes and sends the timestamp value over a 2-bit synchronization channel.

The following figure shows the external connections on the narrow timestamp encoder.
