Overview
The TLK2201BI, produced by Texas Instruments, is a high-speed gigabit Ethernet transceiver designed for ultrahigh-speed full-duplex point-to-point data transmissions. This device is compliant with the IEEE 802.3 Gigabit Ethernet specification and supports data rates from 1.2 to 1.6 Gigabits Per Second (Gbps). It is based on advanced 0.25 µm CMOS technology and is optimized for low power consumption, dissipating less than 200 mW at 1.25 Gbps.
The TLK2201BI performs data serialization, deserialization, and clock extraction functions, making it a crucial component for physical layer interface devices. It operates over various media, including printed-circuit board traces, copper cables, and fiber-optical media, with the ultimate rate and distance of data transfer dependent on the media's attenuation characteristics and environmental noise.
