IDT74FCT88915TT集成電路（IC）的時鐘發(fā)生器PLL頻率合成器規(guī)格書PDF中文資料

DESCRIPTION:

The IDT54/74FCT88915TT uses phase-lock loop technology to lock the frequency and phase of outputs to the input reference clock. It provides low skew clock distribution for high performance PCs and workstations. One of the outputs is fed back to the PLL at the FEEDBACK input resulting in essentially delay across the device. The PLL consists of the phase/frequency detector, charge pump, loop filter and VCO. The VCO is designed for a 2Q operating frequency range of 40MHz to f2Q Max.
