MK3721 Datasheet | Renesas

LOW COST 16.2 TO 28 MHZ 3.3 VOLT VCXO Description The MK3721 series of devices includes the original MK3721S and the new MK3721D. The MK3721D is a drop-in replacement for the MK3721S device. pared 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 ICS’ patented VCXO techniques, the device uses an inexpensive external pullable crystal in the...
