Video Accessory IC Series

The spread of digital cameras, camera-equipped cell phones and other multimedia devices brings a greater number of opportunities for converting video signals into image data. (and viewing on a large TV or PC monitor screen at high resolutions)than ever before. In order to respond to these increased demands, ROHM offers a broad lineup of video Processing LSIs that enable viewing of video signals on TVs and monitors.

Broad Lineup

Sync Separation ICs with built-in AFC Corrects the vertical blurring of OSD characters by eliminating overlapping of the HD and VD pulses A built-in no-adjust AFC circuit improves input noise resistance for increased OSD character position stability Compact 8-pin package can operate using few external parts	Dual VCA for Video Signal Level Adjustment The gain can be freely controlled using DC, making potentiometer obsolete Low gain drift enables high precision adjustment Wide band amp built in, ensuring compatibility with even progressive DVD signals

Video Isolation Amplifier CMRR : -60dB D4 standard compatibility for 300MHz flat frequency characteristics ESD 6kV resistance (HBM)	Dual Video Amplifier Unnecessary large output capacitor for bipolar power supply compatibility Wide bandwidth 10MHz The smallest class package in the industry : MSOP8

NTSC / PAL Analog Video Encoders Initialisation not required Compatible with a wide variety of image output formats (7) (BH7236AF) Generates highly precise burst flag pulses using Becomes technology	High Performance VCOs for Image Sampling 10psec low period-jitter Stable operation, even at high frequencies [evaluated at 1σ (sigma)] Wide oscillation frequency range Compatible with a multitude of applications VCO oscillation frequency switching function Optimal for pixel frequency switching video systems

For portable image equipment Upscaler IC High-quality image, even without flame memory Correspond with NTSC/PAL input formats Maximum 1080p output format (SMPTE274,YCbCr=4:2:2,16bit)
