• Fully addressable 512 Character OSD, simiilar in features to the LM1237/LM1247, with selectable 2 byte character addressing or LM1247 bank select modes
 • Internal 512 character OSD ROM usable as either (a) 384 2-color plus 128 4-color characters, (b) 640 2-color characters, or (c) some combination in between
 • Internal 512 character RAM, which can be displayed as one single or two independent windows
 • Enhanced I2C compatible microcontroller interface to allow versatile Page RAM access
 • OSD Window Fade In/Fade Out
 • OSD Half Tone Transparency
 • Video Data dectection for Auto Centering & Sizing
 • OSD override allows OSD messages to override video and the use of burn-in screens with no video output.
 • 4 DAC outputs (8-bit resolution) for bus controlled CRT bias and brightness
 • Spot killer which blanks the video outputs when VCC falls below the specified threshold
 • Suitable for use with discrete or integrated clamp, with software configurable brightness mixer
 • 4-Bit Programmable start position for internal Horizontal Blanking
 • Horizontal blanking and OSD synchronization directly from deflection signals. The blanking can be disabled, if desired.
 • Vertical blanking and OSD synchronization directly from deflection signals. The blanking width is register programmable and can be disabled, if desired.
 • Power Saving Mode with 65% power reduction
 • Matched to LM246x driver and LM2479/80 bias IC's
