Transceiver IC
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).
