ASM3P2856B 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.
