MK3721 General Description

The MK3721 is ICS/MicroClock's lowest cost, low jitter, high performance 3.3 volt VCXO designed to replace expensive VCXO 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 ICS/MicroClock's patented VCXO techniques, the device uses an inexpensive external pullable crystal in the range of 16.2 - 28 MHz to produce a VCXO output clock at that same frequency.

ICS/MicroClock 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 ICS/MicroClock to eliminate VCXOs, crystals and oscillators from your board.

MK3721DLFTR General Description

LOW 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 MK3721D offers a wider operating frequency range and improved power supply noise rejection.

The MK3721 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 device 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 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 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.

    MK3722 General Description

    The MK3722 is a low cost, low jitter, high performance VCXO and PLL clock synthesizer designed to replace expensive discrete VCXOs and multipliers. 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 ±115 ppm. Using ICS' analog/digital Phase-Locked Loop (PLL) techniques, the device uses an inexpensive 27 MHz pullable crystal input to produce a reference output and a selectable audio clock.

    ICS manufactures the largest variety of VCXO based timing devices for all applications. Consult ICS to eliminate VCXOs, crystals, and oscillators from your board.

    The frequency of the on-chip VCXO is adjusted by an external control voltage connected to VIN. Because VIN is a high impedance input, it can be driven directly from an PWM RC integrator circuit.

    MK3722 Maximum Ratings

    Stresses above the ratings listed below can cause permanent damage to the MK3722. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
