PI6C485352FAE

Clock Buffers, Drivers Overview

The PI6C485352FAE is a high-performance, low-skew LVPECL fanout buffer manufactured by Diodes Incorporated. It features two selectable differential inputs and translates signals to twelve pairs of differential LVPECL outputs. The device supports maximum output frequencies up to 500 MHz with propagation delay under 4 ns and output-to-output skew less than 100 ps. It operates on 2.5V or 3.3V power supplies within an ambient temperature range of -40°C to +85°C. The component is housed in a 48-pin TQFP package.

Clock Buffers, Drivers Feature Summary

• Twelve pairs of differential LVPECL outputs for clock distribution
• Selectable differential CLK and /CLK inputs accepting LVDS, LVPECL, LVHSTL, SSTL, and HCSL levels
• Low output-to-output skew (<100 ps) and part-to-part skew (<500 ps)
• Pin-to-pin compatible with ICS85352I

Clock Buffers, Drivers Applications

• Networking systems including switches and routers
• High frequency backplane based computing platforms
• Telecommunications platforms requiring differential to LVPECL translation

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'E' indicates Pb-free and Green packaging status as defined in the manufacturer's documentation. Confirm that the FA package code corresponds to the 48-pin, 276-mil wide TQFP physical dimensions. Ensure compatibility checks are performed against legacy ICS85352I designs if pin-for-pin substitution is required.

Clock Buffers, Drivers Selection Notes

Select this component when a 2:12 differential clock multiplexer with LVPECL outputs is required. The input stage accommodates various logic levels including LVDS and HCSL, allowing flexibility in source signal types. Verify that the system power rails support both VCC (3.3V ±10%) and VCCO (2.5V/3.3V) requirements simultaneously.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C485352 series of clock buffers. The 'FA' suffix denotes the 48-pin TQFP package type, while the 'E' suffix specifies Pb-free and Green manufacturing compliance. It serves as a direct replacement for the ICS85352I in existing designs.

Clock Buffers, Drivers Replacement Considerations

The datasheet explicitly states pin-to-pin compatibility with the ICS85352I. Designers replacing legacy components should verify that the new part meets the same thermal and electrical specifications for their specific application environment.
