The MK3711D is a drop-in replacement for the original MK3711S device. Compared to these earlier devices, the MK3711D offers a wider operating frequency range and improved power supply noise rejection. Used in conjunction with an external pullable quartz crystal, this monolithic integrated circuit replaces more costly hybrid (canned) VCXO devices. The MK3711 is designed primarily for data and clock recovery applications within end products such as ADSL modems, set-top box receivers, and telecom systems. The MK3711D exhibits a moderate VCXO gain of 120ppm/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. Since VIN is a high impedance input, it can be driven directly from an PWM RC integrator circuit. Frequency output increases with VIN voltage input. The usable range of VIN is 0 to 3V.
