SiTime Corporation Differential Oscillators SIT9375AE-04B2-1810-100.000000

The SiT9375 is a differential oscillator with an integrated MEMS resonator designed for low-jitter applications requiring standard frequencies from 25 MHz to 644.53125 MHz. It offers FlexSwing output signaling with independent control of voltage swing and DC offset, and integrates on-chip regulators to eliminate external LDOs. The device supports LVPECL, LVDS, HCSL, and low-power HCSL signaling, with factory-programmable options for frequency, stability, voltage, and enable functionality. It is available in 2.0 x 1.6 mm, 2.5 x 2.0 mm, and 3.2 x 2.5 mm packages and operates over a temperature range of -40°C to 105°C. Typical phase jitter is 150 fs RMS from 12 kHz to 20 MHz, with 9 fs/mV typical PSNR. The SiT9375AE-04B2-1810-100.000000 variant uses a 1.8 V supply, ±30 ppm frequency stability, and 2.5 x 2.0 mm package with active-high enable.
