Description
The STCCP27A receiver converts the subLVDS
clock/datastream (up to 416 Mbps throughput
bandwidth) back into parallel 8 bits of CMOS/
LVTTL. The device recognizes the CCP 32bit
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 52 MHz) is transmitted
in parallel with data. Input and Output data are
rising edge strobe. 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 to 10μA the
Maximum Current Consumption making this
device ideal for portable applications like Mobile
Phone, Portable Battery Equipment. Two
dedicated I
2
C lines are provided to translate
bidirectional controls from camera and μC
devices. The STCCP27A 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
STCCP27A is characterized for operation over
the commercial temperature range -40°C to 85°C.
