MK3721DLFTR Overview
Clock ICs are packaged using the Tape & Reel (TR) method. In the 8-SOIC (0.154, 3.90mm Width) package, there is an embedded clock generator. In this case, Crystal is designed to be the input of the clock generator. To access the electronic component's full performance, 1 circuits are implemented. The frequency generator has a maximum frequency of 28MHz. Thanks to the Surface Mount, this electric component can easily be installed on a panel. There are 3.15V~3.45V available for use with this clock PLL. Test statistics suggest setting the ambient temperature at 0°C~70°C, which is 0°C~70°C. There are several logic levels in CMOS logic that can be used with this clock generator. It is possible to classify this electronic component as a Voltage Controlled Crystal Oscillator (VCXO). The related electrical components for the base part number MK3721 can be found below.
