IDT5V50015 Datasheet, PDF (1/9 Pages) Integrated Device Technology – LOW EMI CLOCK GENERATOR

LOW EMI CLOCK GENERATOR
DATASHEET
IDT5V50015
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.
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
