DS92LX2121SQX/NOPB

The DS92LX2121SQX/NOPB is a high-speed, high-efficiency transceiver designed for high-speed T1/E1 line transmission applications. Interface-Serializer, Deserializer (SerDes) technology is used to process electronic signals at speeds up to 1.544 Mbps or 2.048 Mbps respectively. In addition, this device also supports low-speed pulse-code modulation (PCM) data transmission, which is used in applications such as 2-wire E1 or ISDN PRI. The DS92LX2121SQX/NOPB also provides a transmission buffer depth of 64 bytes to ensure data integrity.

The DS92LX2121SQX/NOPB is an ideal choice for systems designers looking for a reliable solution to manage multiple digital transmission links. The device is designed with a low jitter output and high power-efficient operation to ensure reliability and lower power consumption. Its dual-interface mode enables compatibility with different transmission media, allowing flexible protocol implementation and helping designers to manage the implementation of multi-channel systems. In addition, the device provides three types of clock interfaces for clock synchronization of data transmission and reception. These features help designers build cost-effective, low-power systems.

The DS92LX2121SQX/NOPB integrates a real-time serial communications processor (SCPR), which is capable of managing multiple physical layer interfaces. The SCPR handles both the hardware level signals and the transport layer operations. The SCPR includes a data link layer controller (DLC) to control the transmit and receive functions for packets and control commands. The DS92LX2121SQX/NOPB also provides a direct memory access (DMA) engine to reduce the load on the SCPR. This engine ensures optimized packet transfers and management of data flow.

The DS92LX2121SQX/NOPB is equipped with an integrated scrambler/descrambler that supports 8-bit or 16-bit framing and CRC error checking. The scrambler/descrambler is used to improve the bit-error rate in digital signaling and reduce jitter. It also supports scrambling on the transmit path and descrambling on the receive path to reduce data errors. In addition, the device offers three loopback modes for diagnostic purposes.

The DS92LX2121SQX/NOPB is part of a complete solution for high-speed, high-efficiency serial communication applications. It provides designers with the required features to manage multiple channels, low jitter output, and flexible protocol implementation. As a result, systems designers can use this transceiver solution to build cost-effective and low-power systems for digital signal transmission.
