The TLK100 is a single-port Ethernet PHY for 10BaseT and 100Base TX signaling. It integrates all the physical-layer functions needed to transmit and receive data on standard twisted-pair cables. This device supports the standard Media Independent Interface (MII).
The TLK100 Ethernet PHY provides 10BASE‑T and 100BASE‑TX connectivity with integrated features such as auto‑MDIX, programmable LEDs, cable diagnostics, and a 25 MHz clock output. It operates over a temperature range of –40 °C to 85 °C and consumes less than 200 mW typical power.
The device is supplied in a 48‑pin TQFP package (7 mm × 7 mm) and includes a full set of interfaces: Serial Management (MDIO/MDC), MAC data, clock, LED, JTAG, and reset/power‑down pins. Jumper options allow configuration of PHY address, auto‑negotiation mode, and LED behavior. Electrical specifications and pin descriptions are detailed for designers integrating the TLK100 into industrial, automotive, or general embedded applications.
