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
• Packaged in 16 pin narrow SOIC
• Uses an inexpensive 20.0 MHz crystal
• Eight selectable frequencies up to 200 MHz
• Duty cycle of 50% typical
• +3.3V operating voltage
• 25mA output drive capability at TTL levels
• Compatible with TI DSP devices

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 33Ω 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.
