SiTime Corporation Differential Oscillators SiT9501A-B210003

The SiT9501 is a differential oscillator with an integrated MEMS resonator for low-jitter applications at standard frequencies from 25 MHz to 644.53125 MHz. It supports LVPECL, LVDS, HCSL, low-power HCSL, and FlexSwing signaling with factory-programmable options for frequency, stability, supply voltage, and output enable. The device offers 45 fs RMS typical phase jitter and 9 fs/mV typical PSNR. It operates over a temperature range of -40°C to 105°C and is available in 2.0 x 1.6 mm, 2.5 x 2.0 mm, and 3.2 x 2.5 mm packages. Power supply options include 1.8 V, 2.5 V, and 3.3 V with a wide continuous voltage range. The SiT9501A-B210003 variant conforms to the series specifications and is packaged in a 2.0 x 1.6 mm form factor with FlexSwing signaling referenced to VDD, a supply voltage of 2.5 V ± 5%, and a frequency stability of ±25 ppm.
