SM5050A

NIPPON PRECISION CIRCUITS INC.

Single-output Clock Generator IC

OVERVIEW

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 C

and C

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.
