• Manufacturer Part Number: LM2501
• Description: Mobile Pixel Link (MPL) Camera Interface Serializer and Deserializer
• Manufacturer: National Semiconductor

Features and Operation
When the Deserializer’s PD* signal is de-asserted, the WC
output will power up and initialize the serializer and start
transmitting the clock reference. Once the Serializer re-
ceived the clock, it waits seven cycles, and then outputs the

Bus States:
Logic Low — 5Idata flowing from the Receiver to the
Logic High — Idata flowing from the Receiver to the Driver
Power Off — No Current flowing in the interconnect

clock signal. Seven cycles later, the Serializer’s PLL will
begin to lock if PCLK is present.
When the Deserializer’s PD* signal is asserted, the WC
signal is turned off.
