SiTime Corporation Differential Oscillators SiT9121AI-2B2-33E27.000000

SiT9121 is a high-performance differential oscillator supporting frequencies from 1 MHz to 220 MHz with LVPECL or LVDS outputs, offering phase jitter as low as 0.6 ps RMS over 12 kHz to 20 MHz and frequency stability options from ±10 ppm to ±50 ppm. It operates over industrial (-40 °C to +85 °C) and extended commercial (-20 °C to +70 °C) temperature ranges, and is available in industry-standard packages of 3.2 x 2.5 mm, 5.0 x 3.2 mm, or 7.0 x 5.0 mm. Supply voltage ranges from 2.25 V to 3.63 V, with slew rate and output levels defined for both signaling types. The device meets MIL-STD-883F, JESD22, and MSL1 moisture sensitivity standards, with a maximum operating junction temperature of 105 °C at 85 °C ambient. The trailing code in the part number indicates specific configuration but does not alter the base specifications listed.
