SI5345D-B-GMR Overview
As a clock IC, it is packaged by the Tape & Reel (TR) method. The 64-VFQFN Exposed Pad package embeds this Clock PLL. The frequency generator is capable of withstanding a maximum temperature of 260 during reflowing. As you can see, it consists of 64 terminations. Basically, this time clock generator needs a voltage of 1.8V. There is a Clock PLL called LVCMOS, LVDS, LVPECL, Crystal which is designed to be the input to this clock generator. Using 1 circuits, the electronic part's full performance can be accessed. RF synthesizers based on this clock provide frequencies up to 350MHz maximum. A Surface Mount-shaped electrical component makes it convenient to mount on a panel. Incorporating CLOCK GENERATOR, PROCESSOR SPECIFIC uPs/uCs/Peripheral ICs, this RF synthesizer features CLOCK GENERATOR, PROCESSOR SPECIFIC. There should be 1.71V~3.47V provided with this RF synthesizer. As determined by the test statistics, the ambient temperature should be set to -40°C~85°C. In this case, we are dealing with a frequency synthesizer that can be used with CML, HCSL, LVCMOS, LVDS, LVPECL logic levels. There are 64 pins that are available on the clock PLL. ALSO REQUIRES 3.3V SUPPLY is included in this frequency generator to enhance clock signal output.
