BH7236AF,BH7240AKV
No.10069EAT06
●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 75Ω 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.
