Product Description
The PCS1P2192A is a clock generator that generates
multiple selectable pixel clock outputs for Video Display
Panel applications from an external 20MHz reference
clock. The PLL based clock generator is specifically
designed to provide zero ppm frequency synthesis error
on all clock outputs. Various pixel clock rates are
selectable through frequency selection pins S[2:0] (Refer
to Frequency Selection Table) The device provides a
reference clock output additionally. Operating Supply
Voltage for this device is 3.3V ± 0.3V. The device is
available in an 8-pin SOIC package.
Application
PCS1P2192A is targeted towards Video Display Panel
(VDP) applications like VGA, SVGA, XGA, WXGA,
UXGA.
