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.

External Components
The MK1711-01 requires a minimum number of external components for proper operation. Decoupling capacitors of 0.1µF should be connected between VDD and GND (pins 3 and 5), as close to the MK1711­01 as possible. A series termination resistor of 33 may be used for the clock output. The input crystal must be connected as close to the chip as possible. The input crystal should be a parallel mode, 20 MHz fundamental, with 20pF load capacitance.
