16-Bit GMSL Serializer with Coax or

Maxim Integrated
As shown in Figure 22, the remote-side device converts
packets going to or coming from the peripherals from
UART format to I2C format and vice versa. The remote
device removes the byte number count and adds or
receives the ACK between the data bytes of I2C. The I2C
bit rate is the same as the UART bit rate.
Interfacing Command-Byte-Only I2C
Devices with UART
The serializer/deserializer UART-to-I2C conversion can
interface with devices that do not require register address-
es, such as the MAX7324 GPIO expander. In this mode,
the I2C master ignores the register address byte and
directly reads/writes the subsequent data bytes (Figure
23). Change the communication method of the I2C mas-
ter using the I2CMETHOD bit. I2CMETHOD = 1 sets
command-byte-only mode, while I2CMETHOD = 0 sets
normal mode where the first byte in the data stream is
the register address.
UART Bypass Mode
In bypass mode, the serializer/deserializer ignore UART
commands from the FC and the FC communicates with
the peripherals directly using its own defined UART pro-
tocol. The FC cannot access the serializer/deserializer
registers in this mode. Peripherals accessed through the
forward control channel using the UART interface need
to handle at least one PCLKIN period Q10ns of jitter due
to the asynchronous sampling of the UART signal by
PCLKIN. Set MS/HVEN = high to put the control channel
into bypass mode. For applications with the FC connect-
ed to the deserializer, there is a 1ms wait time between
setting MS/HVEN high and the bypass control channel
being active. There is no delay time when switching to
bypass mode when the FC is connected to the serial-
izer. Do not send a logic-low value longer than 100Fs to
ensure proper GPO functionality. Bypass mode accepts
bit rates down to 10kbps in either direction. See the GPO/
GPI Control section for GPO functionality limitations. The
control-channel data pattern should not be held low
longer than 100Fs if GPO control is used.
