Product overview
The UT7R995C RadClock is an eight-output PLL clock driver with programmable frequency and phase. It supports clock outputs from 6 MHz to 200 MHz and allows output banks to lead or lag the reference clock. Independent output-bank supplies support 2.5 V or 3.3 V clock signaling while the core operates at 3.3 V. Selectable edge synchronization, multiplication and division ratios, and output drive strength allow the clock network to be configured for the application. Unused output banks can be powered down to reduce dissipation. The UT7R995C uses a quartz-crystal reference.
