LH1687
DESCRIPTION
The LH1687 is a 240-output TFT-LCD source
driver IC used in such products as TV sets. The
LH1687 samples and holds three video signals of
R, G and B by sample and hold circuits
synchronized with the CK, and simultaneously
outputs the LCD drive voltage from all output pins.
FEATURES
• Number of LCD drive outputs : 240
• Output circuit form : Push pull output
• Power save function : By setting the LCD drive
output in a high-impedance condition, the current
source of the LCD drive output circuit is cut off,
which makes low power operation possible
• Sampling timing : Normal sampling operation and
3-point simultaneous sampling operation can be
selected
• Video signal setting : Available for stripe pixel
array panels and delta pixel array panels using
mode setting circuit
• Sampling clock frequency : 25 MHz (MAX.)
• Cascade connection
• Sampling sequence :
Output shift direction can be selected
OS1/OS240 or OS240/OS1
• Output amplitude voltage :
4.8 Vp-p (at 5.0 V supply voltage)
• Supply voltages
– VCCL (for logic system) : +3.0 to +5.5 V
– VCCA (for LCD drive system) : +3.0 to +5.5 V
• Operating temperature : –30 to + 85 ˚C
• Package : 264-pin TCP (Tape Carrier Package)
