NJM2504
VIDEO DIFFERENTIAL OUTPUT DRIVER
QGENERAL DESCRIPTION
The NJM2504 is video differential output driver. The single-end signal
is converted to the differential signal. The single-end signal can be
transmitted by the differential signal by the connection with NJM2507.
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.
