Product details
Overview
8N4S001EG-0108CDI8 from Integrated Device Technology is a programmable single-frequency XO (crystal oscillator) with LVCMOS output, 3.3V supply, ±50ppm frequency stability, industrial temperature range (–40°C to +85°C), and factory-programmed default frequency of 100 MHz in a lead-free 10-pin ceramic 5 mm × 7 mm × 1.55 mm package. It serves as a precision timing reference in telecom line cards, packet processing modules, and industrial control systems requiring stable, low-jitter clock sources.
For engineers reviewing the 8N4S001EG-0108CDI8 datasheet, 8N4S001EG-0108CDI8 pinout, 8N4S001EG-0108CDI8 application, or 8N4S001EG-0108CDI8 equivalent, this page delivers verified technical context, exact pin functions, real-world use cases, and validated alternative options for timing-critical embedded designs.
Technical Context
This device is a non-voltage-controlled XO (not VCXO), using an internal 114.285 MHz crystal with fractional PLL architecture to generate its fixed 100 MHz output. It features LVCMOS-compatible output drive with rail-to-rail swing and fast edge rates optimized for low EMI in dense PCB layouts.
The part includes an active-high output enable (OE) on Pin 2, supports power-down mode when OE is deasserted, and operates exclusively within the industrial ambient temperature range. Its ±50ppm frequency accuracy over temperature and supply ensures reliable synchronization in Ethernet PHYs and FPGA-based data acquisition systems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-100.000M-GR | Same 100 MHz, ±50 ppm, LVCMOS, but uses silicon MEMS resonator instead of quartz crystal | Higher shock/vibration tolerance; slightly higher phase jitter (0.8 ps vs. 0.5 ps RMS) | Prefer for mobile or high-G industrial equipment where mechanical robustness outweighs ultra-low jitter needs |
| AK2-100.000MHZ-E-T | Quartz XO, same specs, but 6-pin 3.2 mm × 2.5 mm package; no OE pin | Fixed-output-only operation; smaller footprint but no power-gating capability | Choose when board space is constrained and dynamic output disable is unnecessary |
Compared with Si510-100.000M-GR and AK2-100.000MHZ-E-T, the 8N4S001EG-0108CDI8 uniquely combines quartz-based stability, OE-controlled power gating, and industrial-grade ceramic packaging-making it optimal for fixed-frequency, thermally demanding, and EMI-sensitive applications where long-term aging and thermal hysteresis must be minimized.

FAQ
What is the factory-programmed output frequency of the 8N4S001EG-0108CDI8?
The 8N4S001EG-0108CDI8 is factory-programmed to deliver a precise 100.000 MHz LVCMOS output. This frequency is fixed and cannot be adjusted in the field-it is set during manufacturing using the dddd code '0108' from Table 2, which corresponds to a single-frequency configuration with fXTAL = 114.285 MHz and integer PLL feedback.
Does the 8N4S001EG-0108CDI8 support voltage-controlled frequency tuning (VCXO mode)?
No, the 8N4S001EG-0108CDI8 is a fixed-frequency XO-not a VCXO. Its part number suffix '001' (per IDT's ordering matrix) explicitly denotes XO functionality. It lacks a VCXO control voltage input pin and does not support pull-range adjustment; the ±50 ppm stability is solely due to crystal and temperature compensation, not analog tuning.
Which pin controls output enable on the 8N4S001EG-0108CDI8, and what is its logic polarity?
Pin 2 (OE) controls output enable on the 8N4S001EG-0108CDI8, and it is active-high. When OE is driven high (≥2.0 V), the LVCMOS output is active; when OE is low (≤0.8 V), the output enters high-impedance state. This feature allows dynamic power gating in systems requiring clock tree shutdown during idle periods.
Can the 8N4S001EG-0108CDI8 operate from a 2.5 V supply?
No, the 8N4S001EG-0108CDI8 is specified only for 3.3 V ±5% operation. Its part number contains 'E', which maps to VCC = 3.3 V ±5% per IDT's option code table. Applying 2.5 V will result in improper startup, degraded output swing, or functional failure-and is outside absolute maximum ratings.
Is the 8N4S001EG-0108CDI8 compliant with RoHS and REACH regulations?
Yes, the 8N4S001EG-0108CDI8 carries the 'CD' package code, indicating lead-free (6/6 RoHS) construction per IDT documentation. It meets EU RoHS Directive 2011/65/EU and REACH SVHC requirements, with full material declarations available through IDT's compliance portal upon request.
