MC100ES6535DT

Clock Buffers, Drivers Overview

The MC100ES6535DT is a low skew, high performance 3.3 V 1-to-4 LVCMOS to LVPECL fanout buffer manufactured by NXP USA Inc. It features two selectable inputs that accept LVCMOS or LVTTL levels and translate them to four differential LVPECL outputs. The device supports a maximum output frequency of 1 GHz with a maximum output skew of 30 ps and part-to-part skew of 190 ps. It operates within a supply voltage range of 3.135 V to 3.8 V and an ambient temperature range of -40 °C to +85 °C. The component is housed in a 20-lead TSSOP package.

Clock Buffers, Drivers Feature Summary

• Translates LVCMOS/LVTTL input levels to differential LVPECL outputs
• Maximum output frequency of 1 GHz
• Internal synchronization for clock enable to eliminate runt pulses
• Low skew characteristics: 30 ps max output skew, 190 ps max part-to-part skew

Clock Buffers, Drivers Applications

• High performance clock distribution applications
• LVCMOS/LVTTL to LVPECL level translation systems
• Multi-channel clock buffering and routing

Clock Buffers, Drivers Procurement Notes

Verify the current manufacturing status as the MC100ES6535DT may be obsolete. Confirm RoHS compliance requirements against the datasheet specifications. Ensure the 20-lead TSSOP package dimensions match the PCB layout constraints. Validate that the 3.3 V operating voltage aligns with the system power design.

Clock Buffers, Drivers Selection Notes

Select this component when LVCMOS or LVTTL sources must drive multiple LVPECL loads. Ensure the application requires a maximum toggle frequency up to 1 GHz. Verify that the 3.3 V supply voltage and -40 °C to +85 °C temperature range meet the environmental needs. Check if the 30 ps output skew specification satisfies the timing budget.

Clock Buffers, Drivers Part Context

This device belongs to the Motorola/Freescale/NXP ES6535 series of timing solutions. It is designed for high-speed digital systems requiring precise clock distribution. The DT suffix indicates the 20-lead TSSOP package variant. The product line focuses on low skew buffers for translating single-ended logic levels to differential ECL-compatible signals.
