LTC6945IUFD#PBF Overview
Clock generator is packaged in the way of Tube. There is a clock generator embedded in the 28-WFQFN Exposed Pad package. There are a total of 28 terminations in this file. Basically, this time clock generator needs a voltage of 3.3V. As the Clock PLL's input, Clock is designed to be used in order to generate the clock signal. An implementation of 1 circuits is required in order to fully utili1e the capabilities of the electrical part. 6GHz is the maximal value for normal operation. Surface Mount-slots make it easy to mount this electronic component on panels. The maximal supply voltage this clock generator would take is 3.45V. As far as the supply voltage is concerned, clock PLL can be used with 3.15V~5.25V. Statistics suggest that the ambient temperature be set at -40°C~105°C, which is what is estimated by the test. An IC that generates clocks specifically for microprocessors, this clock PLL is 28-bits in si28e. The related electronic parts of part number LTC6945 are listed below. A 28 pin is available on the clock PLL. There is a maximum supply voltage of 3.3V that clock generator can handle. PLL or Frequency Synthesis Circuits-type frequency generators are usually classified as this type. PLL FREQUENCY SYNTHESIZER-RF synthesizers are analog integrated circuits that can be classified as analog ICs.
