NJM2507

NJM2507 VIDEO DIFFERENTIAL INPUT RECEIVER sGENERAL 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. sPACKAGE OUTLINE NJM2507RB1 sFEATURES q Operating Voltage 4.5 to 9.5V q Input: Differential signal, Output: Single-end signal q Internal 6dB Amplifier *Differential input mode q Internal 75ohm Driver q Internal SAG Correction Circuit q Bipolar Technology q Package Outline TVSP8 sPIN CONNECTION 1: V+ 2: Power Save 3: Vinp 4: Vinn 5: Vref 6: GND 7: Vsag 8: Vout 1 2 3 4 8 7 6 5 sBLOCK DIAGRAM Vcc PowerSave Vref Bias Vinp Vinn Vout Vsag GND Ver.5 -1- NJM2507 sABSOLUTE 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.
