... OVERVIEW The SM5050A is a single-output clock generator IC that generates standard high-frequency clocks derived from 40MHz crystal oscillator master clock. The high-frequency output stage uses optimized PLL cir- cuits for low jitter output. The oscillator capacitors C 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 ...
