DS90UB914QSQX/NOPB Application Field and Working Principle

The DS90UB914QSQX/NOPB Serializer / Deserializer is an interface circuit that is used for converting a high-speed serial data stream into a parallel or multiplexed pair of output channels. It has many applications, including serial-to-parallel data conversion, inter-chip connectivities, and high-speed industrial Ethernet links. This device is well known for its low power dissipation, fast switching speed, and robust design.

DS90UB914QSQX/NOPB in Serial-to-Parallel Data Conversion

The DS90UB914QSQX/NOPB is well suited for serial-to-parallel data conversion. It has the capability to convert 8-bit or 10-bit serial input streams into up to 8-bit wide or parallel data. It can also be used for serial-to-parallel conversion of a number of other bit width combinations, such as 16-bit, 20-bit, or even 24-bit streams. As long as the total width of the input stream does not exceed 24-bits, the DS90UB914QSQX/NOPB can convert it.

The DS90UB914QSQX/NOPB offers several GPIOs (general purpose inputs/outputs) that can be configured as bidirectional input/outputs, as well as interrupt, control, and status signals. These GPIOs enable the device to be easily integrated into a system design.

DS90UB914QSQX/NOPB Working Principle

The DS90UB914QSQX/NOPB uses a fully synchronous, self-timed architecture to convert serial data into parallel data. The input side of the device converts the serial input into a pair of internal data streams. These streams then flow through the device\'s internal registers and buffers and can be used for various tasks, such as parity and error checking, error correction, and protocol translation.

On the output side, the device can perform several types of data manipulation and formatting. This gives the user the flexibility to configure the device for different applications. For example, the device can be used for data muxing, or for converting 8-bit data into 10-bit data and then back into 8-bit data.

The device also incorporates a number of features that help reduce system cost. These include low power dissipation, low EMI, and tight switching speed. Additionally, like many other serializer/deserializer circuits, the DS90UB914QSQX/NOPB also has built-in ESD protection.

Conclusion

The DS90UB914QSQX/NOPB Serializer/Deserializer is an interface circuit that is used for converting a high-speed serial data stream into a parallel or multiplexed pair of output channels. It is well suited for serial-to-parallel data conversion, as well as other applications. The device uses a self-timed and fully synchronous architecture, and offers several features that help reduce system cost.

Overall, the DS90UB914QSQX/NOPB is an excellent choice for engineers who need a reliable serializer/deserializer circuit for their system designs.
