16-Bit GMSL Serializer with Coax or

Maxim Integrated
write to the device whose address changes (register 0x00
of the serializer for serializer device address change, or
register 0x01 of the deserializer for deserializer device
address change). Then write the same address into the
corresponding register on the other device (register 0x00
of the deserializer for serializer device address change,
or register 0x01 of the serializer for deserializer device
address change).
Three-Level Configuration Inputs
CONF1 and CONF0 are three-level inputs that control
the serial interface configuration and power-up defaults.
Connect CONF1or CONF0 through a pullup resistor to
IOVDD to set a high level, a pulldown resistor to GND to
set a low level, or IOVDD/2 or open to set a midlevel. For
digital control, use three-state logic to drive the three-
level logic inputs.
Configuration Blocking
The serializer can block changes to registers. Set
CFGBLOCK to make all registers read only. Once set, the
registers remain blocked until the supplies are removed
or until PWDN is low.
Compatibility with Other GMSL Devices
The MAX9271 serializer is designed to pair with the
MAX9272 deserializer, but interoperates with any GMSL
deserializer. See Table 12 for operating limitations.
GPIOs
The serializer has five open-drain GPIOs available when
not used as data or configuration inputs. Setting the
GPIO enable bits (register 0x0E) to 1 enables the GPIOs
and internally connects the respective data or configura-
tion input low. Setting the GPIO output bits to 0 pulls the
output low, while setting the bits to 1 leaves the output
undriven, and pulled high through internal/external pullup
resistors. The GPIO input buffers are enabled when the
GPIO is enabled. The input states are stored in register
0x10 (read only). Set GPIO_OUT to 1 when using a GPIO_
as an input.
Local Control-Channel Enable (LCCEN)
The serializer provides inputs for limited configuration of
the device when a FC is not connected. Connect LCCEN
= low upon power-up to disable the local control chan-
nel, and enable the double-function configuration inputs
(Table 13). All input configuration states are latched at
power-up.

MAX9271 FEATURE
GMSL Deserializer
HSYNC/VSYNC encoding
If feature not supported in the deserializer, must be turned off in the serializer.
Hamming-code error correction
If feature not supported in the deserializer, must be turned off in the serializer.
I2C-to-I2C
If feature not supported in the deserializer, must use UART-to-I2C or UART-to-UART.
CRC error detection
If feature not supported in the deserializer, must be turned off in the serializer.
Double input
If feature not supported in the deserializer, data is output as a single word at half the
input frequency.
Coax
If feature not supported in the deserializer, Must connect unused serial input through 200nF
and 50I in series to AVDD, and set the reverse control-channel amplitude to 100mV.
I2S encoding
If supported in the deserializer, disable I2S in the deserializer.
