83904AGI-02LFT

Overview

The ICS83904AGI-02LFT is a low skew, high-performance 1-to-4 Crystal Oscillator/Crystal-to-LVCMOS Fanout Buffer from the HiPerClockS family. It features two crystal oscillator input pairs and one LVCMOS/LVTTL clock input, supporting output frequencies up to 200MHz with a maximum output skew of 40ps at VDD = VDDO = 3.3V. The device operates within an ambient temperature range of -40°C to 85°C and supports multiple supply voltage modes including 3.3V/3.3V, 3.3V/2.5V, 3.3V/1.8V, 2.5V/2.5V, and 2.5V/1.8V. It is available in a 16-lead TSSOP package.

Feature Summary

• Four LVCMOS/LVTTL outputs with 19Ω typical output impedance at VDD = VDDO = 3.3V
• Two crystal oscillator input pairs and one single-ended LVCMOS/LVTTL clock input
• Crystal input frequency range of 12MHz to 38.88MHz with maximum output frequency of 200MHz
• Maximum output skew of 40ps and typical RMS phase jitter of 0.16ps at 25MHz output

Applications

• High-performance clock distribution systems requiring well-defined performance and repeatability
• Applications demanding low skew and low phase noise for precise timing synchronization
• Systems utilizing crystal oscillators or single-ended LVCMOS/LVTTL clock sources

Procurement Notes

Verify that the component matches the specified 16-lead TSSOP package and RoHS 6 lead-free status. Confirm the operating temperature range requirements align with the -40°C to 85°C specification. Ensure supply voltage configurations match the supported modes (e.g., 3.3V/3.3V). Check for any specific ordering suffix requirements if different variants are needed.

Selection Notes

Select this component when low skew and low phase noise are critical for clock distribution. Consider the supported supply voltage combinations (Core/Output) such as 3.3V/3.3V or 2.5V/2.5V. Evaluate the need for dual crystal inputs versus single-ended LVCMOS input based on system design. Ensure the output drive capability meets the load requirements given the 19Ω typical output impedance.

Part Context

The ICS83904AGI-02LFT belongs to the HiPerClockS family of high-performance clock solutions originally developed by IDT (Integrated Device Technology), which was later acquired by Renesas Electronics Corporation. This series is designed for applications requiring precise timing and low jitter characteristics.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Verify compatibility with existing designs if considering alternative fanout buffers from other manufacturers.
