... MK3727C offer a wider operating frequency range and improved power supply noise rejection. The MK3727D is recommended for new designs. The MK3727 series combines the functions of a VCXO (Voltage Controlled Crystal Oscillator) and PLL (Phase Locked Loop) frequency doubler onto a single chip. Used in conjunction with an external pullable quartz crystal, this monolithic integrated circuit replaces more costly hybrid (canned) VCXO devices ...
