¶ Introduction to Neolite SiT912xx :
The SiT912xx is a low phase noise MEMS-based clock generator designed for low-power, low jitter applications. The device has a single clock domain and can drive up to 8 low-skew single-ended output loads or 4 low-skew differential loads. The SiT912xx integrates an internal MEMS resonator as the frequency source for the internal PLL, eliminating the need for an external oscillator o resonator.
The device is fully configurable in output frequency, I/O style (differential and LVCMOS) and individual output enables through the serial interface. Internal monitor flags and alarm conditions are reported through GPIOs. The device is compliant with PCIe Generation 1-6 including configurable spread-spectrum clocking. User-defined, pre-programmed and user-programmable NVM enables a high degree of flexibility and defined startup- configuration. Configurable GPIO pins support state changes such as individual output enable selection.
