The Bt440 is a clock generator for the highspeedBrooktree CMOS RAMDACs.
It interfaces to a low-frequency quartz crystal and " Differential ECL Clock Generation multiplies the crystal frequency by 8x, 16x, 20x, and 32x to generatethe pixel clock sig- .
Divide by 4 of the Clock nals that drive the RAMDAC.
