LOW EMI CLOCK GENERATOR
DATASHEET
IDT5V50017
Description
The IDT5V50017 generates a low EMI output clock from a
clock input. The part is designed to dither the LCD interface
clock for PDAs, printers, DTVs, 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
• Provides a spread spectrum output clock

• Accepts a clock input (provides same frequency dithered
output)
• Down 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
