1 Custom Clock generator for LCD Projector Features • • • • ASM3P2856A ASM3P2856B Product Description ASM3P2856A/B generate the required four custom clock frequencies for the LCD Projector.
An inexpensive 14.
7456MHz crystal is used to generate a 14.
7456MHz used by the microcomputer, a 27MHz used by Video, a non-spread 65MHz, and a centre spread 65MHz clock used by the LCD projector system.
The spread spectrum clock (± 20 ppm) has +/- 0.
5% or +/- 1% spread options.
The spread spectrum clock of ASM3P2856A/B reduces electromagnetic interference (EMI) at the clock source.
This allows significant system cost savings by reducing the number of circuit board...
