Abstract
A method of syncing a serial data stream includes the step of providing a data stream having frames and sub-frames. Each sub-frame is provided with an expected SYNC Word, and there is an expected offset between the SYNC Words in each sub-frame. The data is sent to a plurality of sync modules. Each sync module searches for an expected and different one of the SYNC Words. The sync modules identify an expected SYNC Word, then look for a different one of the SYNC Words at said expected offset from its expected SYNC Word to verify that it has properly identified a SYNC Word.
Claims10
A method of syncing a serial data stream comprising the steps of:
- providing a data stream including frames and sub-frames with each said sub-frame being provided with an expected SYNC Word, and there being an expected offset between said SYNC Words in each said plural sub-frame;
- sending said data to a plurality of sync modules with each of said sync modules searching for an expected and different one of said SYNC Words, and each said module identifying its expected SYNC Word, then looking for a different one of said SYNC Words at said expected offset from its expected SYNC Word to verify that it has properly identified the SYNC Word.
A system comprising:
- a component for generating a serial data stream, said data stream passing into a sync system, and then to a controller;
- the data stream including frames and sub-frames with each said sub-frame provided with an expected SYNC Word, and there being an expected offset between said SYNC Words in each said plural sub-frame;
- and
- said sync system including a plurality of sync modules with each of said sync modules searching for an expected and different one of said SYNC Words, and each said module identifying its expected SYNC Word, then looking for a different one of said SYNC Words at said expected offset from its expected SYNC Word to verify that it has properly identified with a SYNC Word.
