Abstract
A receiver circuit for a tester for electronic devices is provided. The receiver circuit includes a clock receiver that is adapted to receive a source synchronous clock signal from a device under test. The receiver circuit further includes a data receiver that is responsive to the clock circuit. The data receiver is adapted to receive at least one differential data signal from the device under test. The receiver circuit also includes a trigger receiver that is responsive to the clock circuit. The trigger receiver is adapted to receive a trigger signal from the device under test. Finally, the receiver circuit includes a control circuit that is coupled to the trigger receiver. The control circuit is adapted to generate a start alignment capture signal based on the received trigger signal to initiate capture of data received at the data receiver for comparison with expected values.
