16-Bit GMSL Serializer with Coax or
STP Cable Drive
30
Maxim Integrated
Format for Reading
The serializer/deserializer are read using the internally
stored register address as an address pointer, the same
way the stored register address is used as an address
pointer for a write. The pointer autoincrements after each
data byte is read using the same rules as for a write. Thus,
a read is initiated by first configuring the register address
by performing a write (Figure 30). The master can now
read consecutive bytes from the device, with the first data
byte being read from the register address pointed by
the previously written register address. Once the master
sends a NACK, the device stops sending valid data.
I2C Communication with Remote-Side Devices
The serializer supports I2C communication with a periph-
eral on the remote side of the communication link using
SCL clock stretching. While multiple masters can reside
on either side of the communication link, arbitration is
not provided. The connected masters need to support
SCL clock stretching and provide contention detection.
The remote side I2C bit-rate range must be set accord-
ing to the local-side I2C bit rate. Supported remote-side
bit rates can be found in Table 4. Set the I2CMSTBT
(register 0x0D) to set the remote I2C bit rate. If using a
bit rate different than 400kbps, local- and remote-side
I2C setup and hold times should be adjusted by setting
the SLV_SH register settings on both sides.
I2C Address Translation
The serializer supports I2C address translation for up to
two device addresses. Use address translation to assign
unique device addresses to peripherals with limited
I2C addresses. Source addresses (address to translate
from) are stored in registers 0x09 and 0x0B. Destination
addresses (address to translate to) are stored in registers
0x0A and 0x0C.
I2C Broadcast Mode
The serializer supports broadcast commands to control
multiple peripheral devices. Select an unused device
address to use as a broadcast device address. Program
the remote-side GMSL device to translate the broadcast
device address (source address stored in registers 0x09,
0x0B) to the peripheral device address (destination
address stored in registers 0x0A, 0x0C). Any commands
sent to the broadcast address are sent to all designated
peripherals, while commands sent to a peripheral’s unique
device address are sent to that particular device only.
