DS90C185SQ/NOPB series is a pair of single-channel, low-power serializers and deserializers known as S/DES providing flexibility, high speed, and low power consumption. This IC is designed to provide a digital interface between two independent systems over one wire, and consists of two separate chips: one for serializing data, and one for deserializing data. By using this IC, designers can create a single link connection between two digital circuits operating at different clock speeds, or over asynchronous systems.

The DS90C185SQ/NOPB serializer converts 8-bit data into a 10-bit serial stream, while the DS90C185SN/NOPB deserializer converts the serial stream back into 8-bit data. The serializer operates at up to 16 MHz, while the deserializer operates at up to 25 MHz. The serializer and deserializer can operate at different clock speeds, allowing for synchronization between two different digital systems.

The DS90C185SQ/NOPB has a wide range of applications. It can be used to create a single link connection between two digital systems operating at different clock speeds or over asynchronous systems. It can also be used to create communications between two different CPUs, link two different types of communication systems, or between two different products. This IC also has excellent noise immunity, making it ideal for applications that require high data integrity.

The working principle of the DS90C185SQ/NOPB serializer and deserializer is quite simple. The serializer converts 8-bit data into 10-bit serial data, while the deserializer converts the 10-bit serial data back into 8-bit data. The deserializer contains a state machine which can detect the start bit and frame synchronization bytes, as well as a shift register that stores the serial data until it can be read by the controller. The serial stream is then sent to the serializer which then puts it into an appropriate framing format, allowing it to be read by the controller.

The DS90C185SQ/NOPB is a versatile and reliable IC used to provide a digital interface between two digital systems or over asynchronous systems. It is designed to provide flexibility, high speed and low power consumption, making it a great choice for many communication applications. The serializer and deserializer have different clock speeds, allowing them to synchronize data over different clock or asynchronous systems. The IC also has excellent noise immunity, making it ideal for applications that requires high data integrity.
