LTC6954IUFF-3#PBF

LINEAR TECHNOLOGY  LTC6954IUFF-3#PBF  芯片, 时钟分配器, 1.4GHZ, QFN-36

The is a low phase noise, triple output clock distribution divider/driver in 36 pin QFN package. It has three outputs and each output is individually programmable to divide the input frequency by any integer from 1 to 63 and to delay each output by 0 to 63 input clock cycles. The output duty cycle is always 50% regardless of the divide number. It also features "s EZSync system for perfect clock synchronization and alignment every time. The device settings are controlled through an SPI-compatible serial port. It is used in clocking high speed, high resolution ADCs, DACs and data acquisition systems and low jitter clock distribution.
