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 I2C 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.
