PI6C48535-11BLIE

Clock Buffers, Drivers Overview

The PI6C48535-11BLIE is a high-performance, low-jitter LVPECL fanout buffer manufactured by Diodes Incorporated. It translates single-ended crystal or LVCMOS/LVTTL clock inputs into four pairs of differential LVPECL outputs. The device supports selectable CLK and crystal inputs, with the CLK input accepting LVCMOS or LVTTL signal levels. Key electrical specifications include a maximum output frequency of 500 MHz, a typical additive phase jitter of less than 0.05 ps at 156.25 MHz, and a maximum propagation delay of 1.5 ns. It operates on a 3.3V power supply within an ambient temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Translates Crystal/LVCMOS/LVTTL inputs to four pairs of differential LVPECL outputs
• Ultra-low additive phase jitter: < 0.05 ps (typical) at 156.25 MHz
• Maximum output frequency of 500 MHz with 30 ps maximum output skew
• Pin-to-pin compatible with ICS8535-11 and ICS8535-31

Clock Buffers, Drivers Applications

• Clock translation and distribution in data-communications systems
• Telecommunications equipment requiring low-skew clocking
• Crystal oscillator to LVPECL translation interfaces

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'LIE' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure that the 20-pin TSSOP footprint matches the target PCB design constraints. Confirm RoHS compliance status as indicated in the latest product documentation prior to finalizing procurement orders.

Clock Buffers, Drivers Selection Notes

Select this component when a low-jitter solution is required to drive multiple LVPECL loads from a single crystal or CMOS source. The device is suitable for designs needing pin-compatible replacement for legacy ICS8535 parts. Verify that the system power supply remains within the 3.135V to 3.465V range to maintain specified AC characteristics and timing parameters.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C48535 series of fanout buffers designed for high-speed clock distribution. It serves as a bridge between standard logic-level clock sources and high-speed LVPECL receivers. The device integrates crystal oscillator capabilities, reducing the need for external components when using a parallel resonant crystal.

Clock Buffers, Drivers Replacement Considerations

The datasheet explicitly states pin-to-pin compatibility with the ICS8535-11 and ICS8535-31. These parts may be considered direct replacements if electrical parameters such as jitter and skew meet the application requirements.
