PRELIMINARY INFORMATION ICS650-05 HDTV Clock Synthesizer Description Features The ICS650-05 is a low cost, low jitter, high performance clock synthesizer designed to produce 74.175824 MHz and 74.250000 MHz as necessary for HDTV applications. Using our patented analog Phase-Locked Loop (PLL) techniques, the device uses a 27.0 MHz clock or fundamental crystal input to produce buffered, fixed clocks and a selectable frame rate clock for HDTV systems. • • • • Packaged in 20 pin tiny SSOP (QSOP) Input Frequency of 27.0 MHz Zero ppm synthesis error in output clocks Provides fixed 13.5 MHz, dual 27.0 MHz, and 54.0 MHz output clocks with a selectable Frame Rate Clock of 74.175824 MHz or 74.250000 MHz • Ideal for HDTV applications • 3.3 V or 5.0 V operating voltage Block Diagram Clock Synthesis and Control Circuit FRS 27.0 MHz Input Buffer/Crystal Oscillator Output Buffer FRCLK Output Buffer 54.0 MHz Output Buffers 13.5 MHz Output Buffers 27.0 MHz Output Buffer 27.0 MHz OE (all outputs) 1 Revision 081199 Printed 12/4/00 Integrated Circuit Systems • 525 Race Street • San Jose •CA•95126• (408) 295-9800tel • (408) 295-9818fax MDS 650-05 A PRELIMINARY INFORMATION ICS650-05 HDTV Clock Synthesizer Pin Assignment VDD 1 20 VDD X2 2 19 OE X1/ICLK 3 18 FRS VDD 4 17 FRCLK VDD 5 16 VDD GND 6 15 GND NC 7 14 GND 27M 8 13 54M 13.5M 9 12 27M GND 10 11 GND FRCLK Output Select Table (in MHz) FRS Pin 18 0 1 FRCLK Pin 17 74.175824 74.250000 20 pin SSOP (QSOP) Pin Descriptions Pin # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Name VDD X2 X1/ICLK VDD VDD GND NC 27M 13.5M GND GND 27M 54M GND GND VDD FRCLK FRS OE VDD Type P XO XI P P P O O P P O O P P P O I I P Description Connect to +3.3 V or +5.0 V.

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. External Components A minimum number of external components are required for proper operation. A decoupling capacitor of 0.01 µF should be connected between VDD and GND on pins 4 and 6, and 16 and 14, and a 33 Ω terminating resistor may be used on each clock output if the trace is longer than 1 inch. 3 Revision 081199 Printed 12/4/00 Integrated Circuit Systems • 525 Race Street • San Jose •CA•95126• (408) 295-9800tel • (408) 295-9818fax MDS 650-05 A PRELIMINARY INFORMATION ICS650-05 HDTV Clock Synthesizer Package Outline and Package Dimensions 20 pin SSOP Millimeters Symbol E H e b 1.55 1.73 b 0.203 0.305 c 0.190 0.254 D 8.560 8.740 E 3.810 4.000 H 5.840 6.200 e 0.635 BSC 0.410 L 0.016 0.035 Q 0.127 0.250 A c Q Max A h h x 45° D Min L Ordering Information Part/Order Number ICS650R-05 ICS650R-05T Marking ICS650R-05 ICS650R-05 Package 20 pin SSOP 20 pin SSOP Shipping Tubes Tape and Reel Temperature 0 to 70 °C 0 to 70 °C While the information presented herein has been checked for both accuracy and reliability, Integrated Circuit Systems, Incorporated (ICS) 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.
