Description
The ICS673-01 is a low cost, high performance  Phase Locked Loop (PLL) designed for clock  synthesis and synchronization.  Included on the  chip are the phase detector, charge pump, Voltage  Controlled Oscillator (VCO), and two output  buffers. One output buffer is a divide by two of  the other. Through the use of external reference  and VCO dividers (easily implemented with the  ICS674-01), the user can easily customize the  clock to lock to a wide variety of input frequencies. Included on the ICS673-01 are an Output Enable   function that puts both outputs into a high-impedance state, as well as a Power Down feature  that turns off the entire device.
