简  介:DATASHEET LOW EMI CLOCK GENERATOR Description The IDT5V50015 generates a low EMI output clock from a clock or crystal input. The part is designed to dither the LCD interface clock for PDAs, printers, scanners, modems, copiers, and others. Using IDT’s proprietary mix of analog and digital Phase-Locked Loop (PLL) technology, the device spreads the frequency spectrum of the output, reducing the frequency amplitude peaks by several dB. IDT offers many other clocks for computers and computer peripherals. Consult IDT when you need to remove crystals and oscillators from your board. IDT5V50015 Features Packaged in 8-pin SOIC/TSSOP Provides a spread spectrum output clock 135 MHz to 200 MHz operation Accepts a clock input (provides same frequency dithered output) Center spread modulation Peak reduction by 8 dB to 16 dB typical on 3rd through 19th odd harmonics Low EMI feature can be disabled Operating voltage of 3.3 V Advanced, low-power CMOS process Block Diagram VDD S1:0 SSCC 2 PLL Clock Synthesis and Spread Spectrum Circuitry SSCLK ICLK GND IDT LOW EMI CLOCK GENERATOR 1 IDT5V50015 REV F 031109 IDT5V50015 LOW EMI CLOCK GENERATOR SSCG Pin Assignment ICLK VDD GND SSCLK 1 2 3 4 8 7 6 5 VDD S0 S1 SSCC Spread Direction and Percentage Select Table S1 Pin 6 S0 Pin 7 Spread Direction Spread Percentage 0 0 1 1 0 1 0 1 Center Center Center Center ±0.5 ±1.0 ±1.5 ±2.0 8 pin (150 mil) SOIC/TSSOP 0 = connect to GND 1 = connect directly to VDD Pin Descriptions Pi……
