The DS90CR486VS/NOPB is an advanced device that operates as an interface between high speed and low speed peripherals. It is classified as a serializer/deserializer (SERDES) and is used in a variety of applications where data needs to be transmitted efficiently between devices of vastly varying speeds. This article will discuss the applications and working principle of the DS90CR486VS/NOPB.

The DS90CR486VS/NOPB provides a low power, low latency interface solution between two low speed or two high speed peripherals. It is able to convert input signals from two low speed to two high speed, or vice versa, thus allowing efficient communication between devices with vastly different data rates. This enables compatibility between industrial and consumer peripherals, such as an automotive interface and a consumer HD TV interface. Additionally, it is designed for use in applications where low power and small size are required, such as in industrial sensors and mobile product designs.

The DS90CR486VS/NOPB features two high speed differential input ports and two low speed differential output ports. It uses a single-ended data format, allowing it to support up to 12 different input and output channels. In addition, the device utilizes a low-power phase/frequency detector to provide one-to-many clock domain translations, eliminating clock skew between the source and destination devices. The clock recovery circuitry is also capable of automatically detecting changes in input data rate, providing robust and flexible interface solutions.

The working principle of the DS90CR486VS/NOPB is based on clock and data recovery (CDR) technology. This technology enables the device to recover a clock signal from the binary data stream, allowing for reliable data transmission even in challenging environments. The CDR circuitry within the DS90CR486VS/NOPB is designed to be self-calibrating, and provides fast and reliable locking of the recovered clock. The device also features an adjustable jitter attenuator, allowing for improved tolerance to signal integrity problems.
