PI6C4911505LIE

Clock Buffers, Drivers Overview

The PI6C4911505LIE is a high-performance 1:5 LVPECL fanout buffer manufactured by Diodes Incorporated. It supports clock frequencies up to 1.5 GHz with an ultra-low additive phase jitter of typically 0.03 ps (differential, 156.25 MHz, 12 kHz to 20 MHz integration range). The device features two selectable differential inputs compatible with LVPECL, LVDS, HCSL, and CML standards. It operates on a single 3.3V power supply within the industrial temperature range of -40°C to +85°C. Packaged in a 20-pin TSSOP (L), it provides five low-skew outputs for distributing clock signals in networking and computing systems.

Clock Buffers, Drivers Feature Summary

• Five LVPECL outputs supporting up to 1.5 GHz frequency
• Ultra-low additive phase jitter: < 0.03 ps typical
• Two selectable differential inputs (LVPECL, LVDS, HCSL, CML)
• Industrial temperature range (-40°C to +85°C) with 3.3V supply

Clock Buffers, Drivers Applications

• Networking systems including switches and routers
• High-frequency backplane-based computing platforms
• Telecom platforms requiring low jitter clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the ordering code PI6C4911505LIEX corresponds to the specified package and suffixes. Confirm RoHS compliance and lead-free status as defined by Diodes Incorporated. Ensure the application environment stays within the -40°C to +85°C operating temperature range. Check that the input signal levels match the supported differential standards. Validate power supply stability at 3.3V ±10%.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:5 fanout ratio with LVPECL outputs is required. Ensure the system needs support for multiple differential input formats like LVDS or HCSL. Verify that the 1.5 GHz maximum frequency meets the design requirements. Consider the 20-pin TSSOP package constraints for PCB layout. Confirm that the low skew characteristics are sufficient for the target application timing budgets.
