SiT3373 220 MHz to 725 MHz Ultra-low Jitter Differential VCXO Description Features The SiT3373 is a 220.000001 MHz to 725 MHz differential MEMS VCXO engineered for low-jitter applications. Utilizing SiTime’s unique DualMEMS® temperature sensing and TurboCompensation® technology, the SiT3373 delivers exceptional dynamic performance by providing resistance to airflow, thermal gradients, shock and vibration. This device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO. ◼ The SiT3373 can be factory programmed for any combination of frequency, stability, voltage, output signaling, and pull range. Programmability enables designers to optimize clock configurations while eliminating long lead times and customization costs associated with quartz devices where each frequency is custom built. The wide frequency range and programmability makes this device ideal for telecom, networking, and industrial applications that require a variety of pullable frequencies and operate in noisy environments. ◼ ◼ ◼ ◼ ◼ Any frequency between 220.000001 MHz and 725 MHz accurate to 6 decimal places (For frequencies 1 MHz to 220 MHz, refer to SiT3372) Widest pull range options: ±25, ±50, ±80, ±100, ±150, ±200, ±400, ±800, ±1600, ±3200 ppm 0.225 ps RMS phase jitter (typ) over 12 kHz to 20 MHz bandwidth Frequency stability as low as ±15 ppm Wide temperature range support from -40°C to 105°C Industry-standard packages: 7.0 x 5.0 mm, 5.0 x 3.2 mm, 3.2 x 2.5 mm packages Applications ◼ ◼ ◼ Cable Modem Termination System (CMTS), Video, Broadcasting System, Audio, Industrial Sensors, Remote Radio Head (RRH) SATA, SAS, 10/40/100/400 Gbps Ethernet, Fibre Channel, PCI-Express Optical Transport Network (OTN) Refer to Manufacturing Notes for proper reflow profile, tape and reel dimension, and other manufacturing related information.
