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. ■PACKAGE OUTLINE NJM2507RB1 ■FEATURES ● Operating Voltage 4.5 to 9.5V ● Input: Differential signal, Output: Single-end signal ● Internal 6dB Amplifier *Differential input mode ● Internal 75ohm Driver ● Internal SAG Correction Circuit ● Bipolar Technology ● Package Outline TVSP8 ■PIN CONNECTION 1 8 2 7 3 6 4 5 1: V+ 2: Power Save 3: Vinp 4: Vinn 5: Vref 6: GND 7: Vsag 8: Vout ■BLOCK DIAGRAM Vcc PowerSave Vref Bias Vinp Vout Vinn Vsag GND Ver.5 -1- NJM2507 ■ABSOLUTE MAXIMUM RATINGS (Ta=25°C) PARAMETER Supply Voltage Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL + V PD Topr Tstg RATINGS 10 580(Note1) -40 to +85(Note2) -40 to +150 UNIT V mW °C °C (Note 1) At on a board of EIA/JEDEC specification.

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.
