NJM2507
VIDEO DIFFERENTIAL INPUT RECEIVER
■GENERAL DESCRIPTION
The NJM2507 is video differential input receiver. The differential
signal is converted to the single-end signal. The single-end signal can
be transmitted by the differential signal by the connection with
NJM2504.
And, it is converted to the single-end signal by the NJM2507.
The common mode noise can be removed because of the differential
motion transmission, and it is the best for the transmission of car AV
system.

■APPLICATION CIRCUIT
When the receiver is single end input, the NJM2507 becomes GND noise isolator on the transmitter.
Connect GND of the receiver to Vref terminal of the NJM2507. (Note1)
The NJM2507 outputs signal that has canceled the GND noise, because GND reference is the receiver. (Note2)
