Clock Generator For High-frequency Oscillator

The SM5050A is a single-output Clock Generator IC that generates standard high-frequency Clocks derived from a 20 to 40MHz crystal Oscillator master Clock The high-frequency output stage uses optimized PLL cir- cuits for low jitter output. The Oscillator capacitors CG and CD are built-in, realizing a high-frequency output Oscillator by just the connection of a crystal. Two program inputs allows selection from 4 frequency multipli- ers, making the SM5050A able to generate multi-standard frequency Clock outputs. By Seiko NPC Corp.
