85352AYILF

Overview

The 85352AYILF is a clock buffer and driver manufactured by Renesas Electronics Corporation. It functions as a dual LVCMOS/LVTTL-to-differential 2.5V/3.3V LVPECL translator, converting single-ended logic inputs into differential outputs. The device supports selectable CLK0 and CLK1 inputs accepting LVCMOS or LVTTL levels. It operates with a maximum output frequency of 267 MHz and features part-to-part skew of 250 ps maximum. Supply voltages include 3.3V (3.135V to 3.465V) and 2.5V (2.375V to 2.625V). The component is housed in an 8-pin SOIC package and is rated for an ambient operating temperature range of 0°C to 70°C.

Feature Summary

• Dual LVCMOS/LVTTL-to-Differential 2.5V/3.3V LVPECL Translator
• Maximum Output Frequency: 267 MHz
• Part-to-Part Skew: 250 ps (maximum)
• Dual Supply Operation: 3.3V and 2.5V

Applications

• Clock distribution systems requiring level translation
• High-performance digital circuits needing differential signaling
• Systems utilizing LVCMOS or LVTTL sources driving LVPECL loads

Procurement Notes

Verify the current lifecycle status of the 85352AYILF before procurement planning, as distributor records indicate this specific part number may be obsolete. Confirm availability through authorized channels and check for valid replacement components if active stock is unavailable. Ensure compliance with RoHS standards and verify moisture sensitivity level requirements for storage and handling.

Selection Notes

Select the 85352AYILF when interfacing single-ended LVCMOS or LVTTL clocks with differential LVPECL receivers. Ensure the design accommodates both 3.3V and 2.5V supply rails if required. Verify that the 267 MHz maximum frequency meets system timing requirements. Consider the 8-pin SOIC package constraints for PCB layout and thermal management within the 0°C to 70°C operating range.

Part Context

The 85352AYILF belongs to the Renesas 85322 series of clock translators. This series is designed to bridge the gap between standard logic families and high-speed differential signaling standards. The 'YI' suffix typically denotes the 8-pin SOIC package variant, while 'LF' indicates lead-free construction compliant with environmental directives.

Replacement Considerations

Consult Renesas official documentation for direct pin-compatible replacements or functional equivalents within the 85322 family. Verify electrical parameters such as output swing and skew characteristics against the original specification to ensure signal integrity is maintained in the target application.
