ASM3P2856A - Custom Clock generator

General 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.

www.DataSheet4U.com 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 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 layers and shielding that are required to pass EMI regulations.
