STSLVDSP27

The STSLVDSP27 is an 8:1 bit serializer with embedded DPLL. The dual differential line drivers implement the electrical characteristics of sub-low voltage differential signaling (subLVDS), bringing out the serialized data and related synchronous clock signal. The STSLVDSP27 serializer IC is provided with two power supply rails, V_DD and V_IO. The first supply is related to the logic levels of the input data (DIN0-DIN7, CLKIN) and Enables (EN, BYP, DV0, DV1) pins. V_IO provides the power supply to the output current drivers in the device. V_IO is always expected to be a nominal 1.8V. V_DD depends on the application, but will always be equal to or higher than V_IO. In order to minimize static current consumption, it is possible to shut down the transmitters when the interface is not used by setting a power-down (EN) pin. This operation reduces the maximum current consumption to 20A, making this device ideal for portable applications like mobile phones and portable battery equipment. Simplified functionality can be reached using the BYP select pin, which disables the internal DPLL circuitry. When this pin is High the device can work with serialized signals from DIN0 input only. A synchronous CLKIN signal must be provided and it will be put-out using sub- LVDS level by CLKOUT port; the sub-LVDS data will be put-out by DOUT port at a maximum frequency of 208Mhz. This innovative device provides an optimized high-speed link solution from different CMOS sensor devices (parallel or serial outputs) to more advanced graphic controllers in mobile phone applications. All inputs and outputs are equipped with protection circuits against static discharge, providing ESD immunity from transient excess voltage. The STSLVDSP27 is designed for operation over the commercial temperature range -40°C to 85°C.
