Description
The STSMIA832 receiver converts the subLVDS
clock/datastream (up to 650 Mbps throughput
bandwidth) back into parallel 8 bits of
CMOS/LVTTL. The device recognizes the SMIA
32 bit start of frame (SOF), end of frame (EOF),
start of line (SOL) and end of line (EOL)
sequences to generate the H-SYNC and V-SYNC
signals. Output LVTTL clock (up to 82 MHz) is
transmitted in parallel with data. Output data are
rising-edge strobes. This chipset is an ideal
means to link mobile camera modules to
Baseband processors. In order to minimize static
current consumption, it is possible to shut down
the device when the interface is not being used by
a power-down (EN) pin that reduces the
Maximum Current Consumption to 10 µA making
this device ideal for portable applications like
Mobile Phone and Portable Battery Equipment. A
configurable input (Class_Sel) is provided to
select different CLASS (0 or 1,2) mode inside the
SMIA STD specifications.
The STSMIA832 is offered in a µTFBGA package
to optimize PCB space. All inputs and outputs are
equipped with protection circuits against static
discharge, giving them ESD immunity from
transient excess voltage. The STSMIA832 is
characterized for operation over the commercial
temperature range -40°C to 85°C.
