ICS667M-01T

DATASHEET ICS667-01 HDTV CLOCK SYNTHESIZER Description Features The ICS667-01 is a low-cost, low jitter, high-performance PLL clock synthesizer designed to produce the 74.176 MHz clock necessary for HDTV systems. Using IDT’s patented analog Phase-Locked Loop (PLL) techniques, the device accepts a 27 MHz crystal or clock input. The zero ppm synthesis error exactly locks the display to the digital stream. • • • • • • • IDT manufactures the largest variety multimedia clock synthesizers for all applications. Consult IDT to eliminate crystals and oscillators from your board. Packaged in 8-pin SOIC Available in Pb (lead) free package Input frequency of 27 MHz Zero ppm synthesis error in output clock 3.3 V ±5% operating supply Ideal for HDTV applications and oscillator manufacturers Advanced, low power, sub-micron CMOS process NOTE: EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 Block Diagram VDD Clock Synthesis and Control Circuitry 27 MHz crystal or clock input OE CLK 74.17582418 MHz ICLK/X1 Clock Buffer 27.0000 MHz X2 Optional tuning crystal capacitors IDT™ / ICS™ HDTV CLOCK SYNTHESIZER 2 GND 1 ICS667-01 REV D 110409 ICS667-01 HDTV CLOCK SYNTHESIZER CLOCK SYNTHESIZER Pin Assignment ICLK/X1 1 8 X2 VDD 2 7 27M GND 3 6 OE CLK 4 5 GND Pin Descriptions Pin Number Pin Name Pin Type Pin Description 1 ICLK/X1 XI 2 VDD Power Connect to +3.3 V. 3 GND Power Connect to ground. 4 CLK Output 74.17582418 MHz. 5 GND Power Connect to ground. 6 OE Input Output enable.

Crystal connection. Connect to a 27 MHz crystal, or leave unconnected for clock input. External Components Decoupling Capacitor include pads for small capacitors from X1 to ground and from X2 to ground. These capacitors are used to adjust the stray capacitance of the board to match the nominally required crystal load capacitance. Because load capacitance can only be increased in this trimming process, it is important to keep stray capacitance to a minimum by using very short PCB traces (and no vias) between the crystal and device. Crystal capacitors, if needed, must be connected from each of the pins X1 and X2 to ground. A decoupling capacitor of 0.01µF must be connected between VDD and GND on pins 2 and 3. It must be connected close to the ICS667-01 to minimize lead inductance. Pin 5 can be connected to pin 3. No external power supply filtering is required for the ICS667-01. The value (in pF) of these crystal caps should equal (CL -16 pF)*2. In this equation, CL= crystal load capacitance in pF. Example: For a crystal with an 18 pF load capacitance, each crystal capacitor would be 4 pF [(18-16) x 2] = 4. Series Termination Resistor A 33Ω terminating resistor can be used next to the clock outputs for trace lengths over one inch. Crystal Load Capacitors The total on-chip capacitance is approximately 18 pF. A parallel resonant, fundamental mode, AT cut 27 MHz crystal should be used.
