DS92LV1212 16-40 MHz 10-Bit Bus LVDS Random Lock Deserializer with Embedded Clock Recovery April 1999 DS92LV1212 16-40 MHz 10-Bit Bus LVDS Random Lock Deserializer with Embedded Clock Recovery General Description The DS92LV1212 is an upgrade of the DS92LV1210. It maintains all of the features of the DS92LV1210 with the additional capability of locking to the incoming data stream without the need of SYNC patterns. This makes the DS92LV1212 useful in applications where the Deserializer must be operated “open-loop” — without a feedback path from the Deserializer to the Serializer. The DS92LV1212 is designed to be used with the DS92LV1021 Bus LVDS Serializer. The DS92LV1212 receives a Bus LVDS serial data stream and transforms it into a 10-bit wide parallel data bus and separate clock. The reduced cable, PCB trace count and connector size saves cost and makes PCB layout easier. Clock-to-data and data-to-data skews are eliminated since one input receives both clock and data bits serially. The powerdown pin is used to save power by reducing the supply current when the device is not in use. The Deserializer will establish lock to a synchronization pattern within specified lock times but it can also lock to a data stream without SYNC patterns.
