Timing Generator for LCD Panels
For the availability of this product, please contact the sales office.
Description
The CXD2453Q is a timing signal generator for
driving the LCX017AL and LCX023AL LCD panels.
This chip outputs timing signals which support XGA
signals (1024 × 768 dots) and S-XGA signals (1280 ×
1024 dots).
80 pin QFP (Plastic)
Features
• Supports various XGA signals (1024 × 768 dots)
having horizontal scanning frequencies of 44-69kHz
and vertical scanning frequencies of 55 to 85Hz.
• Supports S-XGA (1280 × 1024 dots) pulse
eliminator (horizontal scanning frequency of 69kHz
or less).
• Controls the sample-and-hold position of the
CXA2112R sample-and-hold driver.
• Line inversion and field inversion signal generation
• AC drive of LCD panels during no signal.
