Overview
The TLK2201BIRCPRG4, produced by Texas Instruments, is a high-performance 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 1.0 Gbps to 1.6 Gbps for the TLK2201B and from 1.2 Gbps to 1.6 Gbps for the TLK2201BI variant.
The transceiver performs data serialization, deserialization, and clock extraction functions, making it a crucial component for physical layer interface devices. It operates at a typical rate of 1.25 Gbps, providing up to 1 Gbps of data bandwidth over copper or optical media interfaces.
Although the TLK2201B is no longer in production, it remains an important reference for understanding high-speed Ethernet transceivers.
