DescriptionLOW COST 16.2 TO 28MHZ 3.
The MK3721 series of devices includes the original MK3721S and the new MK3721D. The MK3721D is a drop-in replacement for the MK3721S device. Compared to the earlier device, the MK3721DLFTR offers a wider operating frequency range and improved power supply noise rejection.
The MK3721DLFTR is a low-cost, low-jitter, high-performance 3.3 volt VCXO designed to replace expensive discrete VCXOs modules. The 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 IDT's patented VCXO techniques, the MK3721DLFTR uses an inexpensive external pullable crystal in the range of 16.2 to 28 MHz to produce a VCXO output clock at that same frequency.
IDT of MK3721DLFTR manufactures the largest variety of Set-Top Box and multimedia clock synthesizers for all applications. If more clock outputs are needed, see the MK3732 or MK377x family of parts. Consult IDT to eliminate VCXOs, crystals, and oscillators from your board.
The frequency of the on-chip VCXO of MK3721DLFTR 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. Frequency output increases with VIN voltage input. The usable range of VIN is 0 to 3.3 V.
