The SI5351A-B-GTR with Clock Generators & Support Products I2C Prog, Any Frequency, Any Output, Xtal Ref, 3-Output LVCMOS Clock Gen manufactured by Silicon Labs is an integrated, programmable clock generator designed to support the 10 kHz to 160 MHz frequency range with an integrated Phase-Locked Loop (PLL) and MultiSynth fractional divider. This device has multiple outputs of selectable frequency, allowing for the generation of up to three unique frequencies or frequencies in any arbitrary ratio to each other. Programming this device is easily done with an I2C programming interface, and its flexible clock inputs provide the capability to accept either a crystal reference, or any external clock from the system. The LVHCTM output from the clock generator supports systems operating from 1.8V to 3.3V voltages. In addition, the device eliminates the need for any external components such as logic or pull resistor value selections. The SI5351A-B-GTR is ideal for automated and industrial instrumentation applications including industrial automation and embedded systems.
