Working principle of the IDT2305A-1HDC

The working principle of the IDT2305A-1HDC is based on PLL clock synthesizers. The device contains a programmable PLL-clock synthesizer and an output driver circuit, which are driven by an internal clock source. The internal clock source is either an internal crystal oscillator, or an external reference clock. The internal crystalline oscillator operates in the range of 10 kHz to 10 MHz, and the external reference clock operates in the range of 10 kHz to 500 MHz. The PLL-clock generator is configured using an I S bus interface, and the output driver uses differential LVPECL, single-ended, LVDS, and CML output signals.

The output clock frequency of the IDT2305A-1HDC is determined by the ratio of the frequencies of the reference and output clocks, which can be configured in the range of 5.75 kHz to 500 MHz. The output clock frequency can be tuned to suit the exact application requirements and is accurate to within 0.05%. The PLL-clock synthesizer also features a low jitter range of 0.2 ps RMS. The output of the device is highly stable and free from noise and spurious frequencies.
