1. An apparatus comprising:
- an input terminal for receiving an input signal;
a time stamp circuit having an input coupled to the input terminal, the time stamp circuit including a timer and having an output for providing a time stamp based on a value of the timer in response to receiving the input signal;
an encoder including an input coupled to the output of the time stamp circuit and configured to encode the time stamp into a packet; and
a transmitter configured to transmit the packet.

Abstract
A circuit includes an input terminal for receiving an input signal and a time stamp circuit including an input and an output. The input is coupled to the input terminal. The time stamp circuit includes a timer, and the output is for providing a time stamp based on a value of the timer in response to receiving the input signal. The circuit further includes an encoder including an input coupled to the output of the time stamp circuit and configured to encode the time stamp into a packet. The circuit also includes a transmitter configured to transmit the packet.
