MK1711-01
200 MHz Selectable Clock Source
ICR O CLOC K
Features
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 high-
quality output clock up to 200MHz.
• 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
MicroClock manufactures the largest variety of
clock synthesizers for all applications. Consult
MicroClock to eliminate crystals and oscillators
from your board.

Notes: 1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged
exposure to levels above the operating limits but below the Absolute Maximums may affect device reliability.
2. With VDD at 3.3V and CLK at 200MHz.
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 MK1711-
01 as possible. A series termination resistor of 33Wmay 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.
