Custom Clock generator for LCD Projector  
Product Description  
Features  
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  
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.  
Custom Clock Generator for LCD Projector  
Generates EMI optimized clock signals for  
LCD Projector system  
Uses an inexpensive 14.7456 MHz crystal for  
generating the required Outputs  
Frequency outputs:

CLK2 : 14.7456MHz (Zero ppm)  
CLK3 : 65MHz (± 15 ppm)  
CLK4,CLK5 : 65MHz (±15 ppm) Spread  
Spectrum Clock  
ASM3P2856A: +/- 1% centre spread  
ASM3P2856B: selectable +/-1.0% & +/-1.5%  
Centre Spread option  
Applications  
Supply voltage range 3.3V ± 0.3V.  
Available in 16 Pin TSSOP  
Available in Commercial Temperature range  
ASM3P2856A/B is targeted for use in LCD Projectors.
