Low Phase Noise Clock Multiplier

The IDT613 is a low cost, low phase noise, high-performance clock synthesizer for any applications that require low phase noise and low jitter. It is IDT's lowest phase noise multiplier. Using IDT's patented analog and digital Phase-Locked Loop (PLL) techniques, the chip can accept a 25 MHz crystal or clock input, and produces output clocks up to 157.5 MHz. The chip has separate power supplies for the clock outputs, allowing each output to be run at different voltages. It also allows the core of the chip to operate at 3.3 V, while the output clocks run at either 2.5 V or 3.3 V.
