MAX9257A/MAX9258A
Fully Programmable Serializer/Deserializer
with UART/I2C Control Channel
Figure 19. Video and Control Channel Phases (Spread Off)
Detailed Description
The MAX9257A serializer pairs with the MAX9258A
deserializer to form a complete digital video serial link.
The electronic control unit (ECU) programs the registers
in the MAX9257A, MAX9258A, and peripheral devices,
such as a camera, during the control channel phase that
occurs at startup or during the vertical blanking time.
All control channel communication is half-duplex. The
UART communication between the MAX9258A and the
MAX9257A is encoded to allow transmission through
AC-coupling capacitors. The MAX9257A communicates
to the peripheral device through UART or I2C.
The MAX9257A/MAX9258A DC-balanced serializer and
deserializer operate from a 5MHz-to-70MHz parallel
clock frequency, and are capable of serializing and
deserializing programmable 10, 12, 14, 16, and 18
bits parallel data during the video phase. The devices
have two phases of operation: video and control chan-
nel (Figure 19 and 20). During the video phase, the
MAX9257A accepts parallel video data and transmits
serial encoded data over the LVDS link. The MAX9258A
accepts the encoded serial LVDS data and converts
it back to parallel output data. The MAX9257A has
dedicated inputs for HSYNC and VSYNC. The selected
VSYNC edge causes the MAX9257A/MAX9258A to enter
the control channel phase. Nonactive VSYNC edge can
be asserted after eight pixel clock cycles.
