83904AGI-02LF

Overview

The Renesas Electronics 83904AGI-02LF is a low skew, high-performance 1-to-4 Crystal Oscillator/Crystal-to-LVCMOS Fanout Buffer. It features four LVCMOS/LVTTL outputs with a typical output impedance of 19Ω at VDD = VDDO = 3.3V. The device supports selectable single-ended clock or two crystal oscillator inputs, with a crystal input frequency range of 12MHz to 38.88MHz and a maximum output frequency of 200MHz. It offers an output skew of 40ps (maximum) at 3.3V and typical RMS phase jitter of 0.16ps at 25MHz output. Supply voltage modes include core/output combinations of 3.3V/3.3V, 3.3V/2.5V, 3.3V/1.8V, 2.5V/2.5V, and 2.5V/1.8V. Operating temperature ranges from -40°C to 85°C.

Procurement Notes

Verify the component status as the source indicates this product line may be discontinued. Confirm RoHS compliance level (RoHS 5 or RoHS 6) based on specific ordering suffix requirements. Ensure the package type matches the 16-Lead TSSOP specification with dimensions 4.4mm x 5.0mm x 0.92mm. Check for any relevant Product Change Notices regarding assembly site or part marking changes.

Selection Notes

Select this buffer when a 1-to-4 fanout with crystal input capability is required. Ensure the supply voltage configuration matches the system's core and output voltage needs (e.g., 3.3V core with 2.5V outputs). Verify that the crystal frequency falls within the 12MHz to 38.88MHz range. Consider the -40°C to 85°C operating temperature range for environmental suitability.

Part Context

The ICS83904I-02 is part of IDT's HiPerClockS family of High Performance Clock Solutions. It is designed for applications demanding well-defined performance and repeatability. The device integrates selectable single-ended clock or two crystal-oscillator inputs and provides an output enable function to disable outputs into a high-impedance state.
