SiTime Corporation Digitally Controlled Oscillators SiT3907AC-CF-33NM-200.000000

The SiT3907 is a high precision digitally controlled oscillator (DCXO) that generates frequencies from 1 MHz to 220 MHz with programmable pull ranges up to ±1600 PPM. It features LVCMOS/LVTTL-compatible output, three industry-standard package sizes (3.2 mm × 2.5 mm, 5.0 mm × 3.2 mm, and 7.0 mm × 5.0 mm), and programmable drive strength to reduce EMI. The part operates from supply voltages of 1.71 V to 3.63 V, maintains frequency stability within ±25 PPM over temperature and voltage, and exhibits aging of ±5 PPM over 10 years. It supports digital frequency control via a single-pin interface with two operational modes, achieving a frequency update rate up to 25 kHz. RMS period jitter is specified at 1.5 ps to 3 ps depending on conditions, and current consumption is 31 mA to 34 mA under no-load conditions. The device meets MIL-STD-883F, JESD22, and MSL1 standards for environmental robustness.
