LOW DRIVE VOLT VCXO DATASHEET MK3727H The MK3727H is a low drive, low cost, single output Volt VCXO and PLL clock synthesizers designed to replace expensive VCXOs and crystals. The patented on-chip Voltage Controlled Crystal Oscillator accepts a 0 to V input voltage to cause the output clocks to vary by ±115 ppm minimum. Using our analog Phase Locked Loop PLL techniques, the devices uses an external, fundamental mode MHz pullable crystal input to produce output clocks of 27 MHz. The drive parameters are optimized for low EMI. The frequency of the on-chip VCXO is adjusted by an external control voltage input into pin VIN. Because VIN is a high-impedance input, it can be driven directly from an PWM RC integrator circuit. • Packaged in 8-pin SOIC • Operating voltage of V ±5% • Single pullable output clock of 24 to 36 MHz • Uses a fundamental mode 12 to 18 MHz pullable crystal • On-chip patented VCXO with pull range of 230 ppm minimum • VCXO tuning voltage of 0 to V • Low-drive output stage to reduce EMI • Advanced, low-power, sub-micron CMOS process • Available in RoHS 5 green or RoHS 6 green and lead free compliant package NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 Block Diagram X2 12 to 18 MHz Pullable Crystal Voltage Controlled Crystal Oscillator Frequency Clock Doubler 24 to 36 MHz IDT LOW DRIVE VOLT VCXO MK3727H MK3727H LOW DRIVE VOLT VCXO Pin Assignment X1 1 VDD 2 VIN 3 GND 4 8 X2 7 GND 6 NC 5 CLK 8 Pin 150 mil SOIC VCXO AND MULTIPLIER Pin Descriptions Pin Number 4 5 6 7 8 Pin Name VDD VIN GND CLK NC GND X2 Pin Type Pin Description Input Crystal connection.

LOW DRIVE VOLT VCXO

DATASHEET

MK3727H

The MK3727H is a low drive, low cost, single output Volt VCXO and PLL clock synthesizers designed to replace expensive VCXOs and crystals. The patented on-chip Voltage Controlled Crystal Oscillator accepts a 0 to V input voltage to cause the output clocks to vary by ±115 ppm minimum. Using our analog Phase Locked Loop PLL techniques, the devices uses an external, fundamental mode MHz pullable crystal input to produce output clocks of 27 MHz. The drive parameters are optimized for low EMI.

The frequency of the on-chip VCXO is adjusted by an external control voltage input into pin VIN. Because VIN is a high-impedance input, it can be driven directly from an PWM RC integrator circuit.
• Packaged in 8-pin SOIC
• Operating voltage of V ±5%
• Single pullable output clock of 24 to 36 MHz
• Uses a fundamental mode 12 to 18 MHz pullable crystal
• On-chip patented VCXO with pull range of 230 ppm
minimum
