DESCRIPTION

The AZ12010 contains all of the functional elements necessary to implement a Phase-Locked Loop for clock multiplication at frequencies up to 800 MHz. A fixed 32 times multiplication allows the use of low cost crystals or a low frequency reference signal. The output can be divided by two for 16 times net multiplication. The VCSO is differentially or single-ended driven using the chip CML SAW outputs. The dynamic properties of the PLL are under the control of the user through selection of the desired external components.
