DESCRIPTION
The SN65LVDS315 is a camera serializer that
converts 8-bit parallel camera data into MIPI-CSI1 or
SMIA CCP compliant serial signals.
The device converts the parallel 8-bit data to two
sub-low-voltage differential signaling (SubLVDS)
serial data and clock output. The parallel data is
latched in with the pixel clock input DCLK on the
falling clock edge. The control inputs VS and HS are
used to determine line and frame synchronization.
The serialized data is presented on the differential
serial data output DOUT with a differential clock
signal on output CLK. The frequency of CLK is 8× the
DCLK input pixel clock rate.
Flexible printed circuit (FPC) cabling typically
interconnects the SN65LVDS315 with the CSI-1
compliant receiver. Compared to parallel signalling,
the SN65LVDS315 outputs significantly reduce the
EMI of the interconnect.
The SN65LVDS315 supports three power modes
(shutdown, standby and active) to conserve power.
The TXEN input may be used to put the
SN65LVDS315 in a shutdown mode. The
SN65LVDS315 enters an active standby mode if the
input clock, DCLK, stops. This minimizes power
consumption without the need for controlling an
external terminal.
The SN65LVDS315 is characterized for operation
over ambient air temperatures of –40°C to 85°C. All
CMOS inputs offer failsafe operation to protect the
input from damage during power up and to avoid
current flow into the device inputs during power up.
The core supply of the SN65LVDS315 is 1.8 V. To
provide greater flexibility, the camera data inputs
support a supply range from 1.8 V to 3.3 V.
