SiTime
156.25 MHz ultra-low-jitter LVPECL MEMS oscillator, 3.2 x 2.5 mm, -40 to 85°C
The SiTime SiT9365AI-1B2-33E156.250000 is a 156.25 MHz MEMS differential oscillator with LVPECL output. It runs from a 3.3 V ±10% supply, has an output-enable pin, holds ±25 ppm frequency stability and is rated for -40 to +85°C. It comes in a 3.2 x 2.5 mm package, with typical RMS phase jitter of 0.225 ps (12 kHz to 20 MHz). 156.25 MHz is a common reference clock for 10G/25G/100G Ethernet, optical modules, FPGA SerDes and data-center switching equipment.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
How is the part number SIT9365AI-1B2-33E156.250000 decoded?
SiT9365 = family, A = revision, I = industrial -40 to 85°C, 1 = LVPECL, B = 3.2 x 2.5 mm package, 2 = ±25 ppm, 33 = 3.3 V, E = output-enable, 156.250000 = 156.25 MHz. Without a packing suffix the code denotes bulk packing, which SiTime offers for sampling only; production orders use a tape-and-reel suffix (e.g. T).
Is this part AEC-Q100 qualified?
No. The SiT9365 datasheet does not state AEC-Q100 qualification; it is an industrial-grade device.
