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).

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.

Applications

LCD projectors, etc.
