CLM1201 is a single-chip, single-port 10/100Mbps Ethernet physical layer transceiver developed with great dedication by Chiplon Microelectronics.It supports media independent interfaces MII and RMII simplified media independent interfaces. CLM1201 realizes all the 10/100Mbps Ethernet physical layer functions, including the physical layer encoding sub-layer, physical medium attachment, the twisted-pair physical medium-related sub-layer TP-PMD, 10Base-TX encoding, decoder, and twisted-pair media access unit TPMAU. CLM1201 also supports the automatic MDIX function; it supports the PECL pseudo-emitter-coupled logic interface for connecting external 100Base-FX fiber optic transceivers. This chip adopts advanced CMOS technology to meet the requirements of low voltage and low power consumption. It uses on-chip digital signal processing (DSP) technology, and this chip can perform outstandingly under all conditions. 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 (-40℃ ~ 85℃) working temperatures.
