Overview
The SN65CML100DR, produced by Texas Instruments, is a high-speed translator/repeater designed to support various high-speed network routing applications. This device provides level translation from LVDS (Low-Voltage Differential Signaling) or LVPECL (Low-Voltage Positive Emitter-Coupled Logic) to CML (Current-Mode Logic), and it can repeat CML signals. It operates at signaling rates up to 1.5 Gbps, making it suitable for demanding high-speed data transmission environments.
