27 MHz And 54 MHz 3.3 Volt VCXO

The MK3720D is a drop-in replacement for the MK3720S and MK3720A devices. Compared to these earlier devices, the MK3720D offers a wider operating frequency range and improved power supply noise rejection. The MK3720 is a low cost, low jitter, high-performance 3.3 volt VCXO and PLL Clock Synthesizer designed to replace expensive 13.5, 27, or 54 MHz VCXOs The patented on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3.3 V input voltage to cause the output Clocks to vary by 100 ppm. Using our patented VCXO and Analog Phase-Locked Loop (PLL) techniques, the device uses an inexpensive external 13.5 MHz pullable crystal input to produce output Clocks of 13.5 MHz, 27 MHz, and 54 MHz. The MK3720D exhibits a moderate VCXO gain of 120 ppm/V typical, when used with a high-quality external pullable quartz crystal. 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 a PWM RC integrator circuit. MK3720D is a drop-in upgrade to the earlier MK3720S and MK3720A devices Packaged in 8-pin SOIC Available in Pb (lead) free package Operating voltage 3.3 V (5%) Output Clocks of 54, 27, and 13.5 MHz Uses an inexpensive 13.5 MHz external crystal On-chip patented VCXO with pull range of 200 ppm (minimum) VCXO tuning voltage of 0 to 3.3 V 12 mA output drive capability at TTL levels Advanced, low power, sub-micron CMOS process MK3720D is recommended for new designs By Integrated Device Technology
