LTM2881-Slide14

The DC-to-DC converter powers all of the internal components and provides a regulated 5V output supply, and provides surplus power via the VCC2 pin, to other support circuits the application might require, such as network activity LEDs. The internal power solution is sufficient to support the transceiver interface at its maximum specified load and data rate, and external pins are supplied for extra optional decoupling.  The slew rate mode (/SLO) pin toggles the low EMI edge filters for 250kbps data rate on and off. The DOUT and DIN pins, provide a general purpose isolated output to the system’s logic. The LTM2881 also provides VL, the 1.62V to 5.5V logic supply pin for convenient level shifting to logic interfacing.
