85310AYI-01LFT

Overview

The Renesas 85310AYI-01LFT is a low-skew, high-performance 1-to-10 differential-to-LVPECL/LVHSTL fanout buffer. It translates differential input signals to 2.5V or 3.3V LVPECL levels without external bias networks on the output. The device features selectable differential input pairs (CLKX/NCLKX) that accept LVPECL, LVDS, LVHSTL, SSTL, and HCSL interface levels. Key electrical parameters include a maximum output frequency of 700MHz, typical output skew of 30ps, typical part-to-part skew of 140ps, and typical propagation delay of 2ns. Additive phase jitter is typically less than 0.13ps RMS. It operates from a single supply voltage range of 2.375V to 3.8V for LVPECL mode or -3.8V to -2.375V for ECL mode, with an ambient operating temperature range of -40°C to 85°C.

Procurement Notes

Verify the specific suffix 'AYI' against the manufacturer's current datasheet to confirm package type and lead-free status. Confirm RoHS compliance details directly with the supplier documentation. Check for any product lifecycle notices such as obsolescence or last-time buy notifications prior to procurement.

Selection Notes

Select this component when a 1-to-10 fanout ratio is required with low skew characteristics. Ensure the system power supply matches the 2.375V to 3.8V range for LVPECL operation. Verify that the input signal levels are compatible with the selectable CLKX/NCLKX pairs. Consider thermal management requirements for the SOIC-20 package if operating at high ambient temperatures.
