DESCRIPTION

The SCAN921260 integrates six deserializer devices

into a single chip. The SCAN921260 can

simultaneously deserialize up to six data streams that

have been serialized by the Texas Instruments

SCAN921023 Bus LVDS serializer. The device also

includes a seventh serial input channel that serves as

a redundant input.

Each deserializer block in the SCAN921260 operates

independently with its own clock recovery circuitry

and lock-detect signaling.

The SCAN921260 uses a single +3.3V power supply

with an estimated power dissipation of 1.2W at 3.3V

with a PRBS-15 pattern. Refer to the Connection

Diagrams for packaging information.
