Description

Features

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. 

MicroClock manufactures the largest variety of 

clock synthesizers for all applications. Consult 

MicroClock to eliminate crystals and oscillators 

from your board. 

• 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

Electrical Specifications

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 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.
