Description
The MK1711-01 is a low cost, low jitter, high
performance, high speed PLL clock synthesizer
designed for high-frequency applications. Using
MicroClock’s analog and digital Phase-Locked
Loop (PLL) techniques, the device uses an
inexpensive 20 MHz crystal to generate a highquality output clock up to 200MHz.
MicroClock manufactures the largest variety of
clock synthesizers for all applications. Consult
MicroClock to eliminate crystals and oscillators
from your board.
200 MHz Selectable Clock Source
Features
