83056AGILFT

Overview

The 83056AGILFT is a low skew, 1-to-4 multiplexed differential/LVCMOS-to-LVCMOS/LVTTL fanout buffer manufactured by Renesas Electronics Corporation. It features selectable clock inputs that accept either differential or single-ended input levels, including LVPECL, LVDS, LVHSTL, HCSL, SSTL, LVCMOS, and LVTTL. The device provides four LVCMOS/LVTTL outputs with a nominal output impedance of 7Ω. It supports a maximum output frequency of 350MHz and operates on core/output supply modes such as 3.3V/3.3V, 3.3V/2.5V, 3.3V/1.8V, and 3.3V/1.5V. The component is housed in a 16-pin TSSOP package.

Feature Summary

• Low skew 1-to-4 multiplexed fanout buffer with selectable differential or single-ended inputs
• Maximum output frequency of 350MHz with guaranteed part-to-part skew of 700ps (maximum)
• Supports multiple input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL, LVCMOS, and LVTTL
• Internally synchronized clock enable to eliminate runt pulses during asynchronous assertion/deassertion

Applications

• Clock distribution networks requiring voltage translation between different logic families
• Systems demanding well-defined performance and repeatability for timing-critical applications
• Multiplexing differential or single-ended clock sources to drive multiple downstream loads

Procurement Notes

Verify the specific suffix 'AGILFT' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure compatibility with the required operating temperature range and supply voltage modes before procurement. Cross-reference the part number with current availability status as older revisions may be obsolete.

Selection Notes

Select this component when a low skew solution is needed to multiplex differential or single-ended clocks into four LVCMOS/LVTTL outputs. Verify that the input signal levels match the supported standards (LVPECL, LVDS, etc.) and that the output voltage requirements align with the available VDDO settings (3.3V, 2.5V, 1.8V). Consider the 350MHz maximum frequency limit for high-speed timing applications.

Part Context

The 83056AGILFT belongs to the IDT family of High Performance Clock Solutions, now under Renesas Electronics Corporation. It is designed for applications requiring precise clock distribution and voltage translation. The device is part of a series that includes similar buffers and multiplexers, offering flexibility in input selection and output drive capabilities for complex system timing architectures.

Replacement Considerations

Functional replacements within the same family should maintain the 1-to-4 multiplexed architecture and support for differential/single-ended inputs. Verify pin compatibility and electrical specifications, particularly output skew and maximum frequency, when substituting with other models from the Renesas clock buffer portfolio.
