Renesas 8N4S001EG-0108CDI

Overview

8N4S001EG-0108CDI from Integrated Device Technology is a single-frequency, factory-programmed XO (crystal oscillator) with LVCMOS output, 3.3V supply, ±50ppm frequency accuracy, and 100MHz default output. It uses a 114.285MHz internal crystal and fractional PLL architecture, housed in a lead-free 10-pin ceramic 5mm × 7mm × 1.55mm package for industrial-temperature operation (−40°C to +85°C).

For engineers reviewing the 8N4S001EG-0108CDI datasheet, 8N4S001EG-0108CDI pinout, 8N4S001EG-0108CDI application, or 8N4S001EG-0108CDI equivalent, this page delivers verified specifications, package details, real-world timing use cases, and validated alternative options for telecom clocking, FPGA reference clocks, and embedded control systems.

Technical Context

The 8N4S001EG-0108CDI implements a fractional-N PLL architecture referenced to an internal 114.285MHz fundamental-mode crystal, enabling precise 100MHz output generation with low jitter. Its fixed configuration includes LVCMOS-compatible output drive strength and integrated output enable (OE) controlled at Pin 2.

No external programming interface exists - all functionality is factory-set per order code. The device operates exclusively as a crystal oscillator (XO), not a VCXO, and therefore lacks voltage-controlled tuning capability or pull range specification.

FAQ

What is the output type and voltage level of the 8N4S001EG-0108CDI?

The 8N4S001EG-0108CDI features an LVCMOS output stage operating from a 3.3V supply, delivering a rail-to-rail square wave with typical 50% duty cycle at 100MHz. It meets standard LVCMOS voltage thresholds (V_OH ≥ 0.9×V_DD, V_OL ≤ 0.1×V_DD) and drives standard CMOS loads without external termination. This output type ensures direct compatibility with FPGA, ASIC, and microcontroller clock inputs.

Is the 8N4S001EG-0108CDI a VCXO or an XO?

The 8N4S001EG-0108CDI is a fixed-frequency crystal oscillator (XO), not a voltage-controlled XO (VCXO). Its order code ends in "001", which IDT designates for XO devices. It has no tuning voltage input, and its ±50ppm stability is specified over temperature and aging - not a pull range. The "E" in the part number denotes ±50ppm accuracy, consistent with XO grading, not VCXO functionality.

What does the "0108" in 8N4S001EG-0108CDI indicate?

The "0108" suffix in 8N4S001EG-0108CDI is the default frequency code per IDT's ordering matrix. Per Table 2, code 0108 corresponds to a single-frequency configuration with 100.000MHz output, using the 114.285MHz internal crystal and fractional PLL architecture. It also specifies ±100ppm pull range - though irrelevant for this XO variant - and confirms factory programming with non-changeable configuration (L-suffix implied by final digit "8" in context of CDI packaging).

Does the 8N4S001EG-0108CDI support spread-spectrum clocking?

No, the 8N4S001EG-0108CDI does not support spread-spectrum clocking (SSC). It is a fixed-frequency XO with no modulation capability, no SSC enable pin, and no factory-programmable spread parameters. Its datasheet and ordering documentation make no mention of center-spread, down-spread, or modulation frequency features - confirming it delivers a spectrally pure 100MHz output optimized for low phase noise, not EMI reduction via spreading.

Can the 8N4S001EG-0108CDI be used in place of a 100MHz fundamental-mode quartz crystal?

No - the 8N4S001EG-0108CDI is a complete oscillator module, not a bare crystal. It integrates oscillator circuitry, PLL, output buffer, and regulation, requiring only power and ground. Replacing a fundamental-mode 100MHz crystal would require redesigning the clock generation path: removing the MCU's internal oscillator circuit, bypassing external load capacitors, and routing the 8N4S001EG-0108CDI's LVCMOS output directly to the clock input pin. It cannot be substituted into a crystal socket.
