85352AYILFT

Overview

The Renesas 85352AYILFT is a dual LVCMOS/LVTTL-to-differential 2.5V/3.3V LVPECL translator IC manufactured by Renesas Electronics Corporation. It features two differential LVPECL outputs and selectable single-ended clock inputs compatible with LVCMOS or LVTTL logic levels. The device supports a maximum output frequency of 267MHz and operates within a part-to-part skew specification of 250ps maximum. It functions on either a 3.3V supply (3.135V to 3.465V) or a 2.5V supply (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 differential 2.5V/3.3V LVPECL outputs
• Selectable CLK0, CLK1 LVCMOS/LVTTL clock inputs
• Maximum output frequency of 267MHz
• Part-to-part skew: 250ps (maximum)

Applications

• System clock distribution requiring LVCMOS/LVTTL to LVPECL translation
• Embedded systems with space constraints due to small outline packaging
• High-performance applications prioritizing low power consumption

Procurement Notes

Verify the current status of the 85352AYILFT as distributor records indicate it may be obsolete. Confirm availability through authorized channels and check for recommended replacement components if active stock is unavailable. Ensure the selected package variant matches the required thermal and mechanical specifications for the target application.

Selection Notes

Select this component when a compact solution is needed to translate single-ended digital clock signals into differential LVPECL formats. It is suitable for designs requiring operation at either 2.5V or 3.3V logic levels. Consider the 0°C to 70°C commercial temperature range and ensure the 267MHz frequency limit meets the system timing requirements.
