LM1237AAF/NA
150 MHz I2C Compatible RGB Preamplifier with Internal 254 Character OSD and 4 DACs
LM1237
150 MHzI2C Compatible RGB Preamplifier with Internal
254 Character OSD and 4 DACs
General DescriptionThe LM1237 pre-ampisan integrated CMOS CRT preamp. hasanI2C compatible interface which allows controlofall
the parameters necessaryto directly setup and adjust the
gain and contrastin the CRT display. Brightness and bias
canbe controlled through the DAC outputs which are well
matchedtothe LM2479 and LM2480 integrated bias clamp
ICs. The LM1237 preampis also designedtobe compatible
withthe LM246x high gain driver family.
Black level clampingofthe video signalis carriedout directly the AC coupled input signal into the high impedance
preamplifier input, thus eliminating the needfor additional
clamp capacitors. Horizontal and vertical blankingof the
outputsis provided. Vertical blankingis optional andits
durationis register programmable.
TheICis packagedinan industry standard24 lead DIP
molded plastic package.
FeaturesI2C compatible microcontroller interface Internal 254 character OSD usableas either(a) 190
2-color plus64 4-color characters,(b) 318 2-color
characters,or(c) some combinationin between. OSD override allows OSD messagesto override video
and the useof burn-in screens withno video input4 DAC outputs (8-bit resolution)for bus controlled CRT
bias and brightness Spot killer which blanksthe video outputs when VCC
falls belowthe specified threshold Suitablefor use with discreteor integrated clamp, with
software configurable brightness mixerH andV blanking(V blankingis optional and has
register programmable width) Power Saving Mode with 80% power reduction Matchedto LM246x driver and LM2479/80 drivers
Applications Low end 15" and 17" bus controlled monitors with OSD 1024x768 displaysupto85Hz requiring OSD capability Very low cost systems with LM246x driver
