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 circuits for low jitter output. The oscillator capacitors C_G and C_D are built-in, realizing a high-frequency output oscillator by just the connection of a crystal. Two program inputs allows selection from 4 frequency multipliers, making the SM5050A able to generate multi-standard frequency clock outputs.
