Product details
Overview
8N3D001EG-0045CDI from Integrated Device Technology is a programmable quad-default-frequency XO (crystal oscillator) with LVCMOS output, 3.3V supply, ±50ppm frequency accuracy, 100MHz/125MHz/100MHz/125MHz default frequencies, and industrial temperature range (–40°C to +85°C), used in telecom line cards requiring stable multi-frequency clock sources.
For engineers reviewing the 8N3D001EG-0045CDI datasheet, 8N3D001EG-0045CDI pinout, 8N3D001EG-0045CDI application, or 8N3D001EG-0045CDI equivalent, key selection criteria include default frequency set, output logic family, supply voltage tolerance, frequency stability over temperature, and OE control timing behavior at Pin 2.
Technical Context
This device implements an integer-feedback PLL architecture using a 100.000MHz internal crystal reference, generating four factory-programmed output frequencies via FSEL[1:0] control pins. It operates without external VCXO tuning voltage, confirming its classification as a fixed-frequency XO-not a VCXO-despite shared package and pinout with VCXO variants.
The oscillator integrates a buffered LVCMOS output driver with rail-to-rail swing, active-low output enable (OE@Pin 2), and supports 100% duty cycle operation across all default frequencies. No spread-spectrum or jitter attenuation features are specified in the source documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Quad-default-frequency crystal oscillator (XO), not voltage-controlled |
| Default Frequencies | 100MHz, 125MHz, 100MHz, 125MHz - selected by FSEL[1:0] inputs |
| Output Type | LVCMOS - compatible with standard CMOS logic interfaces, 3.3V rail-referenced |
| Supply Voltage | 3.3V ±5% - requires stable low-noise 3.3V regulator; no 2.5V support |
| Frequency Accuracy | ±50ppm over –40°C to +85°C - tighter than standard ±100ppm XO grade |
| Package | 10-pin ceramic 5mm × 7mm × 1.55mm - RoHS-compliant, surface-mount |
| OE Control | Active-low output enable at Pin 2 - disables output to high-impedance state when asserted |

Equivalent & Alternatives
The following parts are listed as comparable options for similar crystal oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-AC100M000-GR | Single-frequency (100MHz only); ±20ppm; 3.3V LVCMOS; same 5×7mm package | Lacks quad-frequency flexibility; higher accuracy but no FSEL switching | Select when only one frequency is needed and tighter stability is prioritized over configurability |
| AK2-125.000MHZ-EK | Dual-frequency (100/125MHz); ±50ppm; 3.3V LVCMOS; 4-pin SMD package | Only two frequencies; smaller 2.5×2.0mm footprint; no FSEL pins or OE control | Select for space-constrained designs where only two frequencies suffice and OE gating is unnecessary |
Compared with Si510-AC100M000-GR and AK2-125.000MHZ-EK, the 8N3D001EG-0045CDI uniquely delivers four factory-set frequencies in one device with active output control-enabling dynamic rate switching without external logic or clock muxes.

FAQ
What is the function of the FSEL pins on the 8N3D001EG-0045CDI?
The FSEL0 and FSEL1 pins on the 8N3D001EG-0045CDI are 2-bit digital inputs that select one of four factory-programmed output frequencies (100MHz, 125MHz, 100MHz, 125MHz). These pins are sampled at power-up and after each OE assertion; they do not support dynamic runtime switching without toggling OE.
Is the 8N3D001EG-0045CDI a VCXO or an XO?
The 8N3D001EG-0045CDI is a fixed-frequency crystal oscillator (XO), not a voltage-controlled oscillator (VCXO). Although it shares the same package and pinout as VCXO variants, its ordering code "001" and documentation confirm it lacks VCXO pull range functionality and uses integer PLL feedback only.
What is the output enable behavior of the 8N3D001EG-0045CDI?
The 8N3D001EG-0045CDI features active-low output enable (OE) at Pin 2. When OE is logic low, the OUT pin enters high-impedance state. When OE is logic high, the selected frequency is driven as a rail-to-rail LVCMOS signal. No internal pull-up or pull-down is present on OE.
Can the 8N3D001EG-0045CDI be reprogrammed after shipment?
No. The 8N3D001EG-0045CDI is factory-programmed with its default frequencies and configuration before shipment. The "L" suffix is absent in the part number, and documentation confirms the configuration is non-changeable - no field programming or EEPROM update capability exists.
What is the internal crystal frequency used in the 8N3D001EG-0045CDI?
The 8N3D001EG-0045CDI uses a 100.000MHz internal crystal resonator as its frequency reference. This is confirmed by its placement in Table 3 ("Default Frequency Ordering Information for fXTAL = 100.000MHz, Integer Feedback PLL") and absence from fractional-PLL tables.
