1. An apparatus comprising:
- a transmitting unit configured to operate at a first clock rate;
a receiving unit, configured to operate at a second clock rate that is different from the first clock rate, and arranged to receive data from the transmitting unit;
a frequency generating system configured to generate the second clock rate;
a compensation circuit configured to receive the second clock rate from the frequency generating system, and to synchronize the data transmitted by the transmitting unit at the first clock rate with the second clock rate; and
a test circuit configured to test performance of the apparatus.

Abstract
An apparatus and method are disclosed for testing synchronization of transmission between systems operating at different clock rates. The apparatus includes a transmitting unit configured to operate at a first clock rate, and a receiving unit configured to operate at a second clock rate that is different from the first clock rate. A compensation circuit receives a second clock rate from a frequency generating system, and synchronizes the data transmitted by the transmitting unit with the second clock rate. The synchronized data is then transmitted to the receiving unit.

18. A method comprising:
-
generating data using a transmitting unit that operates at a first clock rate; generating a second clock rate using a frequency generating system, the second clock rate being different from the first clock rate; supplying the second clock rate to a compensation circuit; synchronizing the data received from the transmitting unit with the second clock rate using the compensation circuit; outputting synchronized data to a receiving unit at the second clock rate; and verifying accurate reception of the synchronized data at the receiving unit. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
