SiTime Corporation Differential Oscillators SiT9121AC-2D3-33N2.200000

The SiT9121 is a high-performance differential oscillator generating frequencies from 1 MHz to 220 MHz with frequency stability as low as ±10 ppm and RMS phase jitter of 0.6 ps over a 12 kHz to 20 MHz bandwidth. It supports LVPECL and LVDS output signaling, operates from a 2.25 V to 3.63 V supply, and is available in industry-standard packages of 3.2 × 2.5 mm, 5.0 × 3.2 mm, and 7.0 × 5.0 mm. The device meets industrial temperature range (-40 °C to +85 °C) and extended commercial temperature range (-20 °C to +70 °C) specifications. It complies with MIL-STD-883F, JESD22, and MSL1 at 260 °C for mechanical shock, vibration, temperature cycling, solderability, and moisture sensitivity. First-year aging is ±2 ppm at 25 °C, and 10-year aging is ±5 ppm at 25 °C.
