ICS1574B
User Programmable Laser Engine Pixel Clock Generator
Description
The
ICS1574B
is a very high performance monolithic phase-
locked loop (PLL) frequency synthesizer designed for laser
engine applications. Utilizing ICS鈥檚 advanced CMOS mixed-
mode technology, the
ICS1574B
provides a low cost solution
for high-end pixel clock generation for a variety of laser en-
gine product applications.
The pixel clock output (PCLK) frequency is derived from the
main clock by a programmable resettable divider.
Operating frequencies are fully programmable with direct
control provided for reference divider, feedback divider and
post-scaler.
Features
鈥?/div>
Supports high resolution laser graphics. PLL/VCO
frequency re-programmable through serial interface
port to 400 MHz; allows less than 鹵1.5ns pixel clock
resolution.
Laser pixel clock output is synchronized with
conditioned beam detect input
Ideal for laser printer, copier and FAX pixel clock
applications
On-chip PLL with internal loop filter
On-chip XTAL oscillator frequency reference
Resettable, programmable counter gives glitch-free
clock alignment
Single 5 volt power supply
Low power CMOS technology
Compact 鈥?16-pin 0.150" skinny SOIC package
User re-programmable clock frequency supports
zoom and gray scale functions
