83056AGILF

Overview

The 83056AGILF is a low skew, 1-to-4 multiplexed differential/LVCMOS-to-LVCMOS/LVTTL fanout buffer manufactured by Renesas Electronics. It features selectable clock inputs that accept either differential or single-ended input levels, including LVPECL, LVDS, LVHSTL, HCSL, LVCMOS, and LVTTL. The device provides four LVCMOS/LVTTL outputs with a maximum output frequency of 350 MHz. Key electrical specifications include a maximum output skew of 35 ps and a part-to-part skew of 700 ps. Typical additive phase jitter RMS is 0.04 ps. It operates on a 3.3 V core supply with configurable output voltages (3.3 V, 2.5 V, 1.8 V, or 1.5 V) and functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Low skew performance with 35 ps maximum output skew and 0.04 ps typical additive phase jitter RMS
• Multiplexed input capability accepting differential (LVPECL, LVDS, LVHSTL, HCSL) or single-ended (LVCMOS, LVTTL) signals
• Configurable output voltage modes supporting 3.3V/3.3V, 3.3V/2.5V, 3.3V/1.8V, and 3.3V/1.5V core/output combinations
• Internally synchronized clock enable to eliminate runt pulses during asynchronous assertion/deassertion

Applications

• High-performance clock distribution in data communication systems
• Fanout buffering for processors and memory interfaces requiring precise timing
• System boards demanding low skew and repeatability for multi-point clock networks

Procurement Notes

Verify component status as the 83056AGILF may be discontinued or obsolete. Confirm RoHS compliance and package type (TSSOP-16) against current manufacturing notices. Check for valid datasheets and PCN documents regarding design changes or end-of-life notifications before procurement planning.

Selection Notes

Select this component when a 1-to-4 fanout buffer with mixed input compatibility is required. Ensure the application supports the 0°C to 70°C operating temperature range. Verify that the 350 MHz maximum frequency meets system requirements. Consider the 7Ω output impedance and skew specifications for signal integrity analysis in high-speed digital designs.

Part Context

The 83056AGILF belongs to the IDT/Renesas High Performance Clock Solutions family, specifically the 8305 series. It is designed as a low skew fanout buffer to replace discrete logic solutions in complex timing architectures. The device integrates multiple input standards into a single package, simplifying board layout for systems transitioning between different clock domains.

Replacement Considerations

Check for direct pin-compatible replacements within the 8305 series or updated Renesas clock buffer portfolios. Verify if newer generations offer improved skew or extended temperature ranges. Consult official substitution guides for any functional differences in input/output configurations.
