Signal Descriptions
I
2
C Bus
Board label:
I2C_CLK, I2C_DATA
Grid location:
H2, H3
Description:
These are the I
2
C (Inter-IC Communication) bus signals between the
μ
C and a serial EEPROM.
There are several different types of data packets.
The clock rate is a 200 kHz, 0 to 5 volt signal.
I2S (Inter-IC Sound) Bus
Board label:
I2S_SCK, I2S_WS, I2S_SD
Grid location:
H2
Description:
This is an I2S (Inter-IC sound) serial bus.
The clock rate is 2.5 MHz.
LIN Bus
Board label:
LIN
Grid location:
A8
Description:
This is the LIN (Local Interconnect Network) bus signal between two LIN transceivers.
The bus speed is 19.2 kbaud. It contains a mix of version 1.x and 2.x frames.
MIL-STD-1553
Board label:
, MIL1553-
Grid location:
C3
Description:
These signals are representative of MIL-STD-1553 bus protocol traf
fi
c for a serial, differential pair running at
1 MHz. Messages consist of one or more 16-bit words, where each word is preceded by a 3
μ
s sync pulse and followed
by an odd parity bit.
MIPI_DATA, MIPI_CLOCK
Board label:
MIPI_DATA, MIPI_CLOCK
Grid location:
H7
Description:
These signals are representative of MIPI D-PHY bus protocol traf
fi
c for a serial differential pair running
at 500 Mb/s.
