DS92LV1023TMSA Interface - Serializers, Deserializers

The DS92LV1023TMSA from Texas Instruments is an integrated quad deserializer / serializer (SerDes) with low jitter and low latency differential inputs. This SerDes is designed for clock and data recovery in advanced communication systems for both line cards and routers. With its low power operation and high data rate support, the DS92LV1023TMSA provides an ideal solution for multiplexing applications.

Application Fields

The DS92LV1023TMSA is ideal for use in high speed Serial RapidIO®, PCI Express, IEEE 802.3 Ethernet, Fibre Channel, Infiniband, and other high-speed serial interconnects. This device supports data rates up to 6.25 Gbps per lane. It also allows for multiplexing multiple data streams, providing low latency and an extended reach. Furthermore, its jitter attenuator reduces phase jitter, and its adaptive de/equalizer recover data over long or unfavorable channels.

This SerDes is also suitable for other embedded applications, such as in mobile and wireless backhaul applications and network processing engines. By allowing for multiplexing, the increased the data rate of applications without sacrificing the signal integrity. The device is flexible, allowing for a variety of system configurations, such as many-to-one, one-to-many, and one-to-one system topologies.

Working Principle

The DS92LV1023TMSA operates at a bit rate from 200 Mbps to 6.25 Gbps. It includes a differential input receiver, a jitter attenuator, and an output transmitter. The differential inputs are recovered at the jitter attenuator, which reduces the phase jitter. The outputs are generated by the transmitter with the requisite voltage level and the necessary current drive capability. The transmitter is also capable of generating a differential data rate of up to 2.5 V p-p.

The DS92LV1023TMSA also includes an adaptive de/equalizer, which provides signal integrity over long distances and/or through electrical channels with noise and signal distortion. This de/equalizer dynamically adjusts the gain and phase in response to signal distortions, resulting in improved signal integrity and reduced bit error rate. Other features of the DS92LV1023TMSA include an adjustable loop bandwidth and singleended signal input and output.

The DS92LV1023TMSA also incorporates embedded management functions that can be used for performance monitoring. This includes a loopback function, which checks the quality of data transmission, as well as an eye monitor that regulates the quality of the signal in realtime. It also provides embedded management features for configuration, controlling system time, and diagnostics.

The DS92LV1023TMSA supports a variety of protocols and interfaces, including CDR, PAM-4, 8B/10B, 64B/66B, and Serial RapidIO. It also supports user-defined FIFO widths up to 128 bits, used in applications like active memory addressing and memory mapping.

Conclusion

The DS92LV1023TMSA is a quad deserializer / serializer device with low jitter and low latency differential inputs. It is ideal for use in different applications that demand high data rates and low latency operation, such as in advanced communication systems for both line cards and routers. This SerDes supports a variety of protocols and interfaces, including CDR, PAM-4, 8B/10B, 64B/66B, and Serial RapidIO. With its low power operation and high data rate support, the DS92LV1023TMSA provides an ideal solution for multiplexing applications.
