LA2351M

Overview

The LA2351M is Low-noise transceiver IC for car-LAN. Either a 5Mbps or a 7.5Mbps automotive LAN can be formed by

combining this IC with an automotive LAN protocol chip.

Features

• Combining this IC with protocol IC TMC20040C series* for automotive LAN can compose an automotive LAN.

• Supports both 3-bit digital and staircase signals as the input signal. When a 3-bit digital signal cannot be used for wiring

runs due to EMI considerations, you can provide an R-2R ladder in the vicinity of the protocol chip, use the post-D/A

converter signal for the wiring, and connect that signal to the low-pass filter input.

• Built-in adjustment-free low-pass filter.

• Provides low-noise data communication.

*: The TMC20040C series is IC made of SMSC Japan (Standard Microsystems Kabushiki Kaisha).

Functions

Transmitter block

• D/A converter (3 bit).

• LPF (for prevention of EMI).

• Output driver.

Receiver block

• Receiving amplifier.

• Noise eliminating LPF (for the receive signal).

• Comparator (for waveform shaping).
