DATASHEET
LOW EMI CLOCK GENERATOR
IDT5V50013
Description
Features
The IDT5V50013 generates a low EMI output clock from a
clock 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.
• Packaged in 8-pin SOIC/TSSOP
• Provides a spread spectrum output clock
• 50 MHz to 140 MHz operation
• Accepts a clock input (provides same frequency dithered
output)
• Center spread modulation
IDT offers many other clocks for computers and computer
peripherals. Consult IDT when you need to remove crystals
and oscillators from your board.
• 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
