200 MHz Selectable Clock Source

MicroClock Division of ICS•1271 Parkmoor Ave.•San Jose•CA•95126•(408)295-9800tel•(408)295-9818fax ICROCLOCK Block Diagram 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.

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 Ω 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.
