Video Accessory ICs NTSC / PAL Analog Video Encoders No.10069EAT06 BH7236AF,BH7240AKV Description BH7236AF and BH7240AKV are NTSC/PAL analog video encoders which convert R, G, and B component signals to 6 types video signal format for NTSC and PAL: Composite video output, luminance output, chrominance output and R, G, and B output. The encoders eliminate the need for complicated register settings and require only few external parts. Features 1) BH7236AF RGB analog input. BH7240AKV: RGB 8bit digital input 2) 6 outputs support (V, Y, C, R, G, B, however BH7236AF also supports sync output) 3) NTSC/PAL support 4) 5.0V single power supply 5) Logic input 3.0V to 5.0V 6) Subcarrier input (corresponded to sine-wave and pulse-wave) 7) Built-in 75 driver 8) High-speed DAC (only BH7240AKV) 9) Few external parts 10) LC filter for reducing cross-color (with external parts) 11) Unnecessary Initialization 12) Package (SOP24 :BH7236AF :VQFP48C :BH7240AKV) Applications Video Games, Television Display Terminals, etc. Line up matrix Parameter BH7236AF BH7240AKV Input format R,G,B analog R,G,B digital (Parallel 8bit3) Output format 7output 6 output VOUT : composite video output VOUT :composite video output YOUT : luminance signal output YOUT :luminance signal output COUT : color signal output COUT :color signal output ROUT : Red signal output ROUT :Red signal output GOUT : Green signal output GOUT :Green signal output BOUT : Blue signal output BOUT :Blue signal output SYNCOUT: composite sync output Input DAC(only BH7240AKV) - Built-in(8bit3) Package SOP24 VQFP48C www.rohm.com 2010.06 - Rev.A 1/17 2010 ROHM Co., Ltd.
