Synchronous Communication<br />
• Receiver uses a clock which<br />
is synchronized to the<br />
transmitter clock<br />
• The clock may be transferred<br />
by<br />
– A separate interface circuit<br />
– Encoded in the data<br />
(Ethernet)<br />
• Advantages<br />
– Timing information<br />
accurately aligned to the<br />
received data �� allowing<br />
operation at much higher<br />
data rates<br />
– Receiver can tracks any<br />
clock drift which may arise<br />
(due to temperature<br />
variation)<br />
