| ICROCLOCK 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.

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 0.1F 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. 3 Revision 12087 Printed 12/8/97 MicroClock Division of ICS*1271 Parkmoor Ave.*San Jose*CA*95126*(408)295-9800tel*(408)295-9818fax MDS1711-01B ICROCLOCK Package Outline and Package Dimensions MK1711-01 200 MHz Selectable Clock Source 16 pin SOIC narrow Symbol A b c D E H e h Q Inches Min Max 0.055 0.070 0.013 0.019 0.007 0.010 0.385 0.400 0.150 0.160 0.225 0.245 .050 BSC 0.016 0.004 0.01 Millimeters Min Max 1.397 1.778 0.330 0.483 0.190 0.254 9.779 10.160 3.810 4.064 5.715 6.223 1.27 BSC 0.406 0.102 0.254 E H D Q e b c h x 45 A Ordering Information Part/Order Number MK1711-01S MK1711-01STR Marking MK1711-01S MK1711-01S Shipping packaging tubes tape and reel Package 16 pin SOIC 16 pin SOIC Temperature 0-70C 0-70C While the information presented herein has been checked for both accuracy and reliability, MicroClock Incorporated assumes no responsibility for either its use or for the infringement of any patents or other rights of third parties, which would result from its use.
