PI6C41204ALE

Clock Buffers, Drivers Overview

The PI6C41204ALE is a high-performance LVCMOS or LVTTL to LVPECL clock buffer manufactured by Diodes Incorporated. It features four selectable LVPECL outputs and two input options (CLK0/CLK1). The device supports a maximum output frequency of 266 MHz with a propagation delay of up to 1.9 ns. It operates on a single 3.3V supply within the commercial temperature range of 0°C to +70°C. Packaged in a 20-pin TSSOP, it provides low skew characteristics for precise timing distribution.

Clock Buffers, Drivers Feature Summary

• Converts LVCMOS/LVTTL inputs to four differential LVPECL outputs
• Supports maximum frequencies up to 266 MHz
• Features selectable CLK0 or CLK1 inputs via logic control
• Max output skew of 100 ps and part-to-part skew of 150 ps

Clock Buffers, Drivers Applications

• High-speed data communication systems requiring clock distribution
• Server and storage backplane timing networks
• PCI Express and other high-speed serial interface synchronization

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'ALE' corresponds to the Pb-free, Green commercial grade variant in the 20-pin TSSOP package. Confirm that the operating environment remains within the specified 0°C to +70°C range, as industrial variants carry different suffixes. Ensure power supply stability at 3.3V ± 5% during operation.

Clock Buffers, Drivers Selection Notes

Select this component when transitioning from single-ended CMOS/TTL sources to differential LVPECL loads. The 20-pin TSSOP footprint requires adequate thermal management. Verify that the required skew specifications (100 ps intra-device) align with system jitter budgets. Consider the PI6C41204A if enhanced noise performance is needed compared to the base model.

Clock Buffers, Drivers Part Context

This component belongs to the PI6C41204 family of clock buffers. It serves as a pin-compatible alternative to legacy devices like the ICS8535-01. The 'ALE' designation specifically identifies the lead-free, environmentally compliant version intended for commercial applications, distinguishing it from industrial temperature rated parts.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the Renesas 8535AGI-01LF and 8535AG-01LFT. These alternatives offer similar 2:4 fanout capabilities but require verification of pinout compatibility and electrical parameter alignment before integration.
