MAX9257A/MAX9258A
Fully Programmable Serializer/Deserializer
with UART/I2C Control Channel
Maxim Integrated Products 1
19-5891; Rev 1; 9/11
General Description
The MAX9257A serializer pairs with the MAX9258A
deserializer to form a complete digital video serial link.
The devices feature programmable parallel data width,
parallel clock frequency range, spread spectrum, and
preemphasis. An integrated control channel transfers
data bidirectionally at power-up during video blank-
ing over the same differential pair used for video data.
This feature eliminates the need for external CAN or LIN
interface for diagnostics or programming. The clock is
recovered from input serial data at MAX9258A, hence
eliminating the need for an external reference clock.
The MAX9257A serializes 10, 12, 14, 16, and 18 bits
with the addition of two encoding bits for AC-coupling.
The MAX9258A deserializer links with the MAX9257A to
deserialize a maximum of 20 (data + encoding) bits per
pixel/parallel clock period for a maximum serial-data rate
of 840Mbps. The word length can be adjusted to accom-
modate a higher pixel/parallel clock frequency. The pixel
clock can vary from 5MHz to 70MHz, depending on the
serial-word length. Enabling parity adds two parity bits to
the serial word. The encoding bits reduce ISI and allow
AC-coupling.
The MAX9258A receives programming instructions from
the electronic control unit (ECU) during the control
channel and transmits to the MAX9257A over the serial
video link. The instructions can program or update the
MAX9257A, MAX9258A, or an external peripheral device,
such as a camera. The MAX9257A communicates with
the peripheral device with I2C or UART.
The devices operate from a +3.3V core supply and fea-
ture separate supplies for interfacing to +1.8V to +3.3V
logic levels. These devices are available in 40-lead TQFN
or 48-pin LQFP packages. These devices are specified
over the -40NC to +105NC temperature range.
