ML2652 General Description
The ML2652, 10BASE-T Physical Interface Chip, is a complete physical interface for twisted pair and AUI Ethernet applications. It combines a 10BASE-T MAU, Manchester Encoder/Decoder, and Twisted Pair Interface filters in one monolithic IC. A complete DTE interface for twisted pair Ethernet can be implemented by combining the ML2652, an Ethernet controller, and transformers.
The ML2652 can automatically select between an AUI and twisted pair interface based on Link Pulses. Six LED outputs provide complete status at the physical link. Link pulse testing can be enabled or disabled through the LTP LED Pin.
The unique transmitter design uses a waveform generator and low pass filter to meet the 10BASE-T transmitter requirements without the need for an external filter. The differential current driven output reduces common mode which in turn results in very low EMI and RFI noise.
The ML2652 and ML2653 (28 pin version) are implemented in a low power double polysilicon CMOS technology. The ML2653 does not include the AUI interface.
