ICS83056AGI-01

Clock Buffers, Drivers Overview

The ICS83056AGI-01 is a 6-bit, 2:1 single-ended LVCMOS multiplexer from the HiPerClockS family. It features two selectable clock inputs and six independent outputs with a VDDO supply configurable at 3.3V, 2.5V, or 1.8V for voltage translation. The device operates up to 250MHz with typical additive phase jitter of 0.18ps RMS at 155.52MHz (12kHz–20MHz). Propagation delay ranges from 1.5ns to 4.5ns depending on supply conditions. It includes an output enable pin for high-impedance control and functions within a -40°C to 85°C ambient temperature range.

Clock Buffers, Drivers Procurement Notes

Verify package type upon ordering; the standard suffix 'G' indicates a tube, while 'T' indicates tape and reel packaging. Confirm RoHS compliance requirements by checking for the 'LF' suffix in the part number. Ensure the selected variant matches the required shipping quantity and environmental specifications.

Clock Buffers, Drivers Selection Notes

Select based on required output voltage levels (VDDO) and core voltage (VDD) combinations. Verify that the maximum operating frequency of 250MHz meets system timing requirements. Consider the propagation delay variations across different supply modes when designing critical path delays.

Clock Buffers, Drivers Part Context

This component belongs to the HiPerClockS family of high-performance clock solutions manufactured by IDT (Integrated Device Technology), which was later acquired by Renesas Electronics Corporation. It serves as a specialized timing distribution element for multi-rate data communication systems.

Clock Buffers, Drivers Replacement Considerations

The datasheet lists the 83056AGI-01T, 83056AGI-01LF, and 83056AGI-01LFT as variants differing only in packaging (tape/reel) and lead-free status. No other functional cross-model replacements are documented in the provided source material.

Clock Buffers, Drivers FAQ

How does the Output Enable (OE) pin function?

When the OE pin is LOW, all outputs enter a high-impedance state. When HIGH, the outputs are active.

What is the typical input skew specification?

Input skew (tsk(i)) varies by supply mode but is typically 100ps to 145ps under standard test conditions.

Can unused clock inputs be left floating?

Yes, unused CLK inputs can be left floating, though adding a 1kΩ resistor to ground is recommended for additional protection.
