A test data generator, test system and method thereof are provided. In the example method, parallel test data may be received at a first data rate. The received parallel test data may be converted into serial test data at a second data rate. Noise (e.g., jitter noise, level noise, etc.) may be selectively inserted into the converted serial test data. The noise inserted into the serial test data, which may be configured to operate at a higher data rate than the parallel test data, may allow a device to be tested with higher data-rate test data. The example method may be performed by the example test data generator and/or by the example test system.
