Clockless Link-BD
Clockless Link-BD Serializer
with MIPI and LVDS Interface for Automotive
BU18TL82-M
General Description
BU18TL82-M supports MIPI DSI and LVDS data
transmission by ROHM's original CDR (Clock Data
Recovery) technology. This chip is the serial interface
transmitter IC of the Clockless Link-BD series.
BU18TL82-M converts the MIPI DSI and LVDS data
stream into Clockless Link format transmit through 2
pairs of differential wires.
Flexible Input / Output mode is suitable for a variety of
application interface.
