CLM1211 is a highly integrated Ethernet transceiver developed with great dedication by Chiplon Microelectronics.It complies with the IEEE 802.3 standards of 10Base-T, 100Base-TX and 1000Base-T. It provides all the physical layer functions required for transmitting and receiving Ethernet data packets via CAT.5 UTP cables. Utilizing advanced digital signal processing technology and analog front-end (AFE), it enables high-speed data transmission and reception on UTP cables.Functions such as cross-line detection and automatic correction, polarity correction, adaptive equalization, crosstalk elimination, echo elimination, timing recovery and error correction can all be realized, thereby providing reliable transmission and reception capabilities at rates of 10 Mbps, 100 Mbps or 1000 Mbps. Data transmission between the MAC and the PHY is carried out through the simplified Gigabit Media Independent Interface (RGMII) for 1000Base-T, 10Base-T and 100Base-TX.Supports multiple RGMII signal voltages, including 1.5V and 1.8V, 2.5V, and 3.3V. The product can directly pin to pin replace similar international products without the need to change the circuit board or system software, achieving complete compatibility and replacement. Chiplon Microelectronics has developed its own testing plan to ensure that the factory products meet or even exceed the original specifications, supporting industrial grade (0 ℃~70 ℃) working temperatures.
