.. November 2006 rev0.1 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 microputer, 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...
