SLLS961B – JULY 2009 – REVISED SEPTEMBER 2015 SN65HVDA195-Q1 LIN and Most ECL Physical Interface
1 Features 3 Description The SN65HVDA195 device is the Local Interconnect
Network (LIN) physical interface and MOST ECL
interface, which integrates the serial transceiver with
wake-up and protection features. The bus is a singlewire bidirectional bus typically used for low-speed invehicle networks using data rates to 20 kbps. The
device can transmit with an effective data rate of 0
kbps because it does not have dominant state timeout. The protocol output data stream on TXD is
converted by the SN65HVDA195 into the bus signal
through a current-limited wave-shaping driver as
outlined by the LIN Physical Layer Specification
Revision 2.0. The receiver converts the data stream
from the bus and outputs the data stream through
RXD. The bus has two states: dominant state
(voltage near ground) and the recessive state
(voltage near battery). In the recessive state, the bus
is pulled high by the SN65HVDA195’s internal pullup
resistor and series diode, so no external pullup …
