DS9638CN

The DS9638CN is an integrated High-speed Multi-Channel Differential Bus Driver and Receiver designed for data communication in the field of interface applications. It is designed for differential bus data rates up to 1000 Mbps, and is suitable for all types of inter-system digital communications providing high performance and low power consumption.

The DS9638CN differential bus driver and receiver have been designed to provide multi-channel, one pair of unidirectional differential bus driver and receiver to aid in data communications between systems. The differential bus driver operates at a nominal voltage of 3.3V and has an adjustable supply voltage range of 3.2V to 3.6V. It has a voltage range of ±400mV and output current capability of +/-250mA, allowing it to drive up to four channels with up to 1MHz differential bus data rate. The receiver has an adjustable supply voltage range of 2.8V to 3.7V and an adjustable range of 120mV, 200mV, and +/-500mV, which allows it to receive up to four channels of differential data up to 1MHz.

The DS9638CN has multiple pin-programmable options for data transfer modes and other protocol options, including half-duplex, full-duplex, and simultaneous half-duplex and full-duplex modes. The data transfer mode is selected by setting the appropriate pull up or pull down resistors on the bus. The DS9638CN allows for a wide range of data transfer protocols, including Sercos, SPI, and I2C, along with options such as ID detection and error detection. Additionally, the device has an integrated power-on reset circuit and can be used in self-test mode.

The working principle of the DS9638CN high-speed differential bus driver and receiver is simple and straightforward. In normal operation, the differential bus driver produces an amplified version of the differential bus signal, and the receiver amplifies the original differential bus signal back to its original level. The device also provides for electrostatic discharge, thermal protection, over current and over voltage protection, as well as integrated monitoring and alerting functions. The differential bus driver is designed to accept a variety of differential bus signals, such as data signals, clock signals, control signals and differential reference signals. The signals are transferred through the driver and amplified by a differential amplifier before being output on the output pins of the driver. The receiver accepts the amplified signal and compares it to an internal reference level, and amplifies it back to the original signal level before being output on the receiver pins. The device also provides error detection and status flag options to allow for monitoring of the signals. In summary, the DS9638CN High-speed Multi-Channel Differential Bus Driver and Receiver is a high performance and reliable device designed for data communications in the field of interface applications. It provides for a wide range of data transfer protocols, and is suitable for communication rates of up to 1000 Mbps. The device provides for user configuration options, and integrated monitoring and alerting functions. It is also designed for electrostatic discharge, thermal protection, over current and over voltage protection.
