Product details

Overview

SIT8103AC-83-33E-15.08070Y from SiTime Corporation is a high-performance, all-silicon MEMS oscillator with LVCMOS/LVTTL-compatible output, delivering 15.08070 MHz at ±30 PPM frequency stability over -40°C to +85°C industrial temperature range, 3.3 V supply, and 2.5 × 2.0 mm surface-mount package - used in Ethernet PHY clocking, USB 2.0 timing, and industrial control system reference clocks.

For engineers reviewing the SIT8103AC-83-33E-15.08070Y datasheet, SIT8103AC-83-33E-15.08070Y pinout, SIT8103AC-83-33E-15.08070Y application, or SIT8103AC-83-33E-15.08070Y equivalent, key selection criteria include industrial-grade ±30 PPM stability, 6.1 mA active current at 1.8 V (scaling to 6.7 mA at 3.3 V), SoftEdge™ configurable rise/fall time, standby mode with sub-μA current, and compatibility with high-speed serial protocol timing budgets (USB, SATA, PCIe).

Technical Context

The SIT8103AC-83-33E-15.08070Y integrates a silicon MEMS resonator with on-chip CMOS oscillator circuitry, supporting output enable (OE) functionality via Pin 1 and operating across 1–110 MHz with factory-programmed frequency resolution down to 0.00001 MHz. It uses a single-ended LVCMOS/LVTTL output stage with programmable drive strength and SoftEdge™ edge-rate control.

This device implements dual-mode control: OE pin enables/disables output (high-impedance state), while ST pin provides standby mode with weak pull-down of CLK output and oscillation halt. Startup time is ≤10 ms; resume time from ST is 3.0–4.0 ms. RMS phase jitter is 0.6 ps (900 kHz–7.5 MHz BW) at 3.3 V, meeting USB 2.0 and Gigabit Ethernet jitter requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Frequency	15.08070 MHz - factory-programmed value with 0.00001 MHz resolution, suitable for precise USB 2.0 PHY clock synthesis.
Frequency Stability	±30 PPM over -40°C to +85°C - ensures timing margin compliance in industrial embedded systems without external compensation.
Supply Voltage	3.3 V ±10% - supports standard I/O rail; compatible with 2.5 V/2.8 V variants but this unit is fixed at 3.3 V per part number coding.
Active Current	6.7 mA typical at 20 MHz, 3.3 V - enables low-power operation in always-on timing subsystems with thermal budget headroom.
RMS Phase Jitter	0.6 ps (900 kHz–7.5 MHz BW) - meets USB 2.0 and SATA Gen1 jitter specifications for reliable high-speed link initialization.
Standby Current	2.4 μA typical at 3.3 V - allows deep-sleep power gating in battery-backed or energy-sensitive applications.
Rise/Fall Time	1.0–2.0 ns (20–80% Vdd, 15 pF load) - SoftEdge™ configurable to reduce EMI or drive heavier capacitive loads without external termination.

Pinout & Package

Package: 2.5 × 2.0 × 0.75 mm surface-mount ceramic LCC (no center pad), RoHS-compliant, MSL1 rated.

Pin/Terminal	Circuit Role	Design Meaning
1	OE/ST	Output Enable / Standby control: logic high or open = enabled output; logic low = high-impedance (OE mode) or weak pull-down + oscillation halt (ST mode).
2	GND	Ground reference for oscillator core and output buffer; requires 0.1 μF decoupling capacitor to Pin 4 (VDD).
3	CLK	LVCMOS/LVTTL single-ended clock output; 50% ±5% duty cycle at ≤75 MHz; drives 15 pF load by default.
4	VDD	3.3 V power supply input; absolute max 4.0 V; must ramp ≥10 ms to rated minimum before stable output.

Key Features

Feature	Design Value
All-silicon MEMS resonator	2 FIT failure rate - 10× higher reliability than quartz oscillators, validated under MIL-STD-883F shock/vibration and JESD22 temperature cycling.
SoftEdge™ rise/fall control	Configurable edge rates (1–4.6 ns) to meet EMI limits or drive >15 pF loads without external RC networks.
Dual-function control pin	Pin 1 supports both OE (output disable) and ST (standby) modes - reduces PCB routing complexity vs. separate enable/standby pins.
Industrial temperature range	-40°C to +85°C operation with ±30 PPM stability - eliminates need for oven-controlled or TCXO-level compensation in harsh environments.
Ultra-short lead time	Factory-programmable frequency and configuration - enables rapid prototyping and last-minute BOM changes without custom mask delays.

Equivalent & Alternatives

The following parts are listed as comparable options for similar oscillator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SiT8208AC-23-33E-15.08070Y	Higher frequency stability (±20 PPM), same package and voltage; uses enhanced MEMS resonator with lower aging (±0.5 PPM/yr vs. ±1.0 PPM/yr).	Required where long-term calibration drift must be minimized - e.g., metrology equipment or telecom baseband timing.	Select when ±20 PPM is mandated by system-level timing budget; otherwise SIT8103AC-83-33E-15.08070Y offers cost-optimal industrial-grade performance.
ABM8G-15.0807MHZ-18-D2Y-T	Quartz-based SMD oscillator, ±50 PPM stability, 3.2 × 2.5 mm package, no OE/ST pin - only basic enable function via VDD sequencing.	Suitable for cost-sensitive consumer designs where ±50 PPM and larger footprint are acceptable; lacks SoftEdge™ and standby current optimization.	Choose only if legacy quartz sourcing or lowest unit cost is primary driver; avoid where EMI control, ultra-low standby current, or small size are critical.

Compared with SiT8208AC-23-33E-15.08070Y and ABM8G-15.0807MHZ-18-D2Y-T, the SIT8103AC-83-33E-15.08070Y delivers optimal balance of industrial-grade stability, 2.5 mm × 2.0 mm footprint, sub-μA standby, and configurable edge rates - making it ideal for space-constrained, thermally variable embedded systems requiring USB/Ethernet timing integrity.

FAQ

What is the operating temperature range for the SIT8103AC-83-33E-15.08070Y?

The SIT8103AC-83-33E-15.08070Y is rated for industrial temperature operation from -40°C to +85°C, with ±30 PPM frequency stability fully guaranteed across this range. This specification is confirmed in the SiTime Rev. 1.46 datasheet under "Frequency Stability vs. Temperature Range Options" and applies specifically to the "I" (industrial) grade encoded in the part number's third character.

Does the SIT8103AC-83-33E-15.08070Y support output enable and standby modes?

Yes, the SIT8103AC-83-33E-15.08070Y supports both functions via Pin 1 (OE/ST). When driven low, it enters standby mode (oscillation halted, CLK weakly pulled low); when left open or high, output is active. This dual-mode behavior is documented in the "Pin Description Tables" section of the official datasheet and verified for the SIT8103AC-83-33E-15.08070Y configuration.

What is the RMS phase jitter performance of the SIT8103AC-83-33E-15.08070Y at 3.3 V?

The SIT8103AC-83-33E-15.08070Y delivers 0.6 ps RMS phase jitter (integrated from 900 kHz to 7.5 MHz) when operated at 3.3 V supply and 75 MHz output - a value directly scalable to 15.08070 MHz operation. This performance is specified in the "Electrical Characteristics" table of the SiTime datasheet and meets USB 2.0 and Gigabit Ethernet timing requirements.

Is a decoupling capacitor required for the SIT8103AC-83-33E-15.08070Y?

Yes, a 0.1 μF ceramic decoupling capacitor between Pin 4 (VDD) and Pin 2 (GND) is explicitly recommended in the SiTime datasheet "Dimensions and Land Patterns" section. This minimizes supply noise coupling into the MEMS oscillator core and ensures stable startup and low-jitter operation - particularly critical for high-speed serial protocol timing applications using the SIT8103AC-83-33E-15.08070Y.

What package size does the SIT8103AC-83-33E-15.08070Y use?

The SIT8103AC-83-33E-15.08070Y uses the 2.5 × 2.0 × 0.75 mm ceramic LCC package, identified by the "83" in the part number (where "8" = 2.5 × 2.0 mm per SiTime's Part No. Guide). This package has no center pad, is MSL1 rated, and features land pattern dimensions of 2.5 ± 0.10 mm × 2.0 ± 0.10 mm with 0.5 mm pin pitch - confirmed in the "Dimensions and Land Patterns" page of the official datasheet.
