SiTime Corporation Differential Oscillators SiT9501AC0QPP8-2510-39.062500

The SiT9501 is a differential oscillator with an integrated MEMS resonator, designed for low-jitter applications in networking equipment requiring frequencies from 25 MHz to 644.53125 MHz. It offers 45 fs RMS typical phase jitter for SerDes applications, supports LVPECL, LVDS, HCSL, low-power HCSL, and FlexSwing output signaling, and operates across a wide temperature range of -40°C to 105°C. The device integrates on-chip regulators to filter power supply noise and provides factory-programmable options for frequency, stability, voltage, and output enable. Available package sizes are 2.0 x 1.6 mm, 2.5 x 2.0 mm, and 3.2 x 2.5 mm. Frequency stability options include ±20, ±25, ±30, and ±50 ppm. Supply voltages supported are 1.8 V, 2.5 V, and 3.3 V, with a wide continuous voltage range up to 3.63 V.
