DS80PCI810NJYT

The DS80PCI810NJYT from Texas Instruments is a high-performance, low-power 8-channel linear redriver. It is engineered to support high-speed interface protocols such as PCIe Gen-1, PCIe Gen-2, and PCIe Gen-3, with a maximum data rate of 8 Gbps.

This redriver features advanced configurable signal conditioning, including a Continuous Time Linear Equalizer (CTLE) that provides up to approximately 10 dB of high-frequency boost at 4 GHz. This capability is crucial for opening input eyes that may be closed due to inter-symbol interference (ISI) from interconnect mediums like board traces or copper cables. It also includes a linear output driver with a variable output voltage range up to 1200 mVp-p.

Designed for efficiency, the DS80PCI810NJYT offers low power consumption, typically 70 mW per channel, with an option to power down unused channels. It boasts ultra-low input-to-output latency of 80 ps (typical) and supports seamless link training. Programmability is available via pin selection, EEPROM, or SMBus interface. The device operates from a single supply voltage of 2.5V or 3.3V and has a 4 kV HBM ESD rating.

The redriver is housed in a 54-pin, 10 mm x 5.5 mm WQFN package with a flow-through layout, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C.
