Product details
Overview
SIT8103AI-13-33E-25.00000T from SiTime Corporation is a high-performance, all-silicon MEMS oscillator with LVCMOS/LVTTL output, 25.00000 MHz nominal frequency, ±30 PPM frequency stability over -40°C to +85°C industrial temperature range, 3.3 V supply voltage, and 2.5 × 2.0 mm surface-mount package. It delivers low jitter (4.0 ps RMS period jitter at 75 MHz), ultra-low standby current (0.4–0.8 µA at 1.8 V), and configurable SoftEdge™ rise/fall time for EMI reduction in embedded timing applications.
For engineers reviewing the SIT8103AI-13-33E-25.00000T datasheet, SIT8103AI-13-33E-25.00000T pinout, SIT8103AI-13-33E-25.00000T application, or SIT8103AI-13-33E-25.00000T equivalent, key selection criteria include industrial-grade temperature operation, 3.3 V LVCMOS compatibility, 2.5 × 2.0 mm footprint, ±30 PPM stability, and OE-enabled output control - critical for USB, PCIe, and industrial control clocking.
Technical Context
The SIT8103AI-13-33E-25.00000T implements a MEMS resonator with integrated CMOS oscillator circuitry, supporting output enable (OE) functionality on Pin 1 and delivering rail-to-rail LVCMOS-compatible waveforms. Its SoftEdge™ programmable edge rate reduces EMI without external components while maintaining signal integrity into 15–45 pF loads.
It operates across 1–110 MHz with factory-programmed frequency accuracy, supports 3.3 V ±10% supply, and achieves 2 FIT reliability - 10× better than quartz oscillators. Startup time is ≤10 ms, and resume time from standby is 3.0–4.0 ms, enabling fast system wake-up in power-sensitive designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ABM10AIG-25.000MHZ-10-D2X-T | Quartz-based, ±30 PPM, 2.5 × 2.0 mm, 3.3 V, but higher jitter (15 ps RMS), 10× lower reliability (20 FIT), no OE pin. | Lacks output enable; unsuitable for dynamic clock gating; less robust in vibration-prone industrial enclosures. | Choose only if legacy quartz qualification is mandated and jitter >10 ps is acceptable. |
| SG-8018CE 25.000000MHz TJGA | CMOS-output quartz oscillator, ±30 PPM, 2.5 × 2.0 mm, 3.3 V, OE support, but 12 ps RMS jitter and 15 FIT reliability. | Supports OE but lacks SoftEdge™; requires external filtering for EMI-critical video/audio layouts. | Select when OE is required but MEMS adoption is restricted; verify jitter budget allows 12 ps margin. |
Compared with ABM10AIG-25.000MHZ-10-D2X-T and SG-8018CE 25.000000MHz TJGA, the SIT8103AI-13-33E-25.00000T offers superior jitter (4.0 ps vs. ≥12 ps), 2 FIT reliability, and programmable edge rate - directly improving signal integrity and system uptime in USB, PCIe, and industrial control applications.

FAQ
What is the operating temperature range of the SIT8103AI-13-33E-25.00000T?
The SIT8103AI-13-33E-25.00000T is rated for industrial temperature operation from -40°C to +85°C. This range is confirmed in the SiTime datasheet Rev. 1.46, Table "Frequency Stability vs. Temperature Range Options", where "I" suffix denotes industrial grade and ±30 PPM stability is supported across this full span without derating.
Does the SIT8103AI-13-33E-25.00000T support output enable functionality?
Yes, the SIT8103AI-13-33E-25.00000T supports output enable via Pin 1 (OE/ST). When Pin 1 is driven high or left open, the CLK output is active; when pulled low, the output enters high-impedance state. This feature is documented in the "Pin Description Tables" section of the official SiTime datasheet.
What is the RMS period jitter specification for the SIT8103AI-13-33E-25.00000T?
The SIT8103AI-13-33E-25.00000T has an RMS period jitter of 4.0 ps at 75 MHz with 2.5–3.3 V supply, as specified in the "Electrical Characteristics" table. While the device operates at 25.00000 MHz, this jitter value scales favorably and remains well within USB 3.0 and PCIe Gen3 requirements.
Is a decoupling capacitor required for the SIT8103AI-13-33E-25.00000T?
Yes, a 0.1 µF ceramic capacitor between VDD (Pin 4) and GND (Pin 2) is recommended per SiTime's layout guidance in the "Dimensions and Land Patterns" section. This minimizes supply noise and ensures stable startup and low-jitter operation.
What package size does the SIT8103AI-13-33E-25.00000T use?
The SIT8103AI-13-33E-25.00000T uses the 2.5 × 2.0 × 0.75 mm surface-mount package, indicated by the "13" in its part number per the SiTime Part No. Guide. This is a standard 4-pin ceramic SMD package with no center pad and RoHS-compliant terminations.
