Abstract
A device having a sample-rate converter that may be programmed to generate samples at different rates is synchronized to an external synchronization pulse by temporarily changing the sample rate to a temporary sample rate and then changing the sample rate back to the original sample rate. Synchronization in a reduced amount of time is achieved by determining the interval between the synchronization pulse and one of the output samples and determining a processing time of the device for generating the output samples at a new rate. The system calculates a temporary sample rate based on these calculations that tends to reduce an amount of time to achieve synchronization.
