DS1212+

The DS1212+ is a dual stage, 8-bit rate controlled synchronous one-way data FIFO which is deployed in many applications. It is designed to increase the efficiency of the system by enabling up to two processors to communicate through a single synchronous one-way communication interface. This FIFO is designed for use in real-time DVRs, Asynchronous Transfer Mode (ATM) devices, Technical Broadcast, Digital Audio/Video Surveillance applications and other areas. The DS1212+ is available in 20-pin inline packages and is ideal for low-power applications.

Application Field and Working Principle

The DS1212+ FIFO is used in a wide variety of applications. In each application the controller primarily functions as an address translation and frequency conversion device. Depending on the application, the FIFO will provide data synchronization and data buffering capabilities. It also eliminates the need for a large on-chip addressable memory and reduces the number of interconnect pins for communication systems.

The DS1212+ is a dual stage FIFO, which allows the FIFO to both receive and send data from two different sources. For example, data from one system can flow into the FIFO, while data from another system can flow out of the FIFO. This feature is useful for applications such as DVRs, Asynchronous Transfer Mode (ATM) devices and Technical Broadcast. This FIFO also provides synchronization between two systems. It synchronizes both data and addresses which helps eliminate timing errors that would occur if the data was simply passed between the two systems.

The working principle of the DS1212+ is based on a rate-controlled synchronous one-way transmission architecture. To provide synchronization between two systems, the FIFO uses two pointers, an in-pointer and an out-pointer. The FIFO is equipped with a 8-bit rate-control circuit which controls the frequency of the data transferred between the two systems. This frequency is determined by the clock speed of the DS1212+. The DS1212+ is also equipped with an 8-level priority rate control circuit, which is used to prioritize the incoming data. This feature allows the FIFO to manage the data traffic between two systems and helps to improve data throughput.

The DS1212+ is designed for low-power applications and is available in 20-pin inline packages. Its low power consumption and small physical size make it ideal for applications where space is limited. Additionally, the DS1212+ can be easily integrated into existing systems, reducing integration time and cost.
