8532AKI-31LFT

Overview

The Renesas 8532AKI-31LFT is a dual LVCMOS/LVTTL-to-differential 2.5V/3.3V LVPECL translator designed for high-performance clock distribution. It features two differential LVPECL outputs and selectable single-ended clock inputs (CLK0, CLK1) that accept LVCMOS or LVTTL levels. The device supports a maximum output frequency of 267MHz with a part-to-part skew of 250ps maximum. It operates on a 3.3V supply (3.135V to 3.465V) and a 2.5V supply (2.375V to 2.625V), functioning within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Dual differential 2.5V/3.3V LVPECL outputs
• Selectable LVCMOS/LVTTL clock inputs (CLK0, CLK1)
• Maximum output frequency of 267MHz
• Part-to-part skew of 250ps (maximum)

Applications

• High-speed digital systems requiring clock translation
• Space-constrained applications needing low power and high performance
• Data communication equipment

Part Context

The 8532AKI-31LFT belongs to the 85322 family of clock translators from Renesas Electronics. This series provides solutions for translating single-ended logic levels to differential LVPECL signals, addressing needs for signal integrity in high-frequency designs. The specific 'AKI' variant denotes the industrial/commercial temperature range and package configuration associated with this product line.

Replacement Considerations

The datasheet indicates that the 85322 series devices are obsolete. Designers should consult Renesas for current alternative components or migration paths, as direct substitutes may require verification of pin compatibility and electrical specifications.
