853S12AKILF

Overview

The Renesas 853S12AKILF is a low skew, 1-to-12 differential-to-LVPECL fanout buffer belonging to the HiPerClockS family. It accepts CML, LVPECL, and SSTL differential inputs via PCLK/nPCLK pairs and provides twelve LVPECL outputs. The device operates on 2.5V or 3.3V supplies within a -40°C to +85°C temperature range. Key electrical parameters include a maximum part-to-part skew of 250ps and a maximum propagation delay of 680ps. It is housed in a 32-lead VFQFPN package (5.0 x 5.0 mm) with a 0.5mm pitch.

Feature Summary

• 1-to-12 differential fanout buffer supporting LVPECL, CML, and SSTL input levels
• Low skew performance with guaranteed part-to-part skew of 250ps maximum
• Dual voltage operation for 2.5V and 3.3V core supplies
• High gain differential amplifier accepting peak-to-peak input voltages as small as 150mV

Applications

• Clock distribution networks requiring well-defined performance and repeatability
• Systems demanding low skew characteristics for synchronized data paths
• High-performance computing and telecommunications infrastructure
