Texas Instruments CDC906PW

Description
The CDC906 is a high-performance 3:6 PLL-based clock synthesizer/multiplier/divider. It offers user-programmable PLL frequencies and easy in-circuit programming via an SMBus data interface. The wide PLL divider ratio allows for 0-PPM output clock error. The device can generate precise video (27 MHz or 54 MHz) and audio system clocks from multiple sampling frequencies (fs = 16, 22.05, 24, 32, 44.1, 48, 96 kHz).
