Summary: Designed to support PCle 5.0, CXL 2.0, UPI 2.0 and interfaces up to 32Gbps.

DS320PR410 Texas Instruments

The Texas Instruments DS320PR410 quad-channel linear redriver is a low-power, high-performance redriver designed to support PCle 5.0, CXL 2.0, UPI 2.0 and interfaces up to 32Gbps. These linear redrivers or repeaters support AC coupled interfaces such as DP, SATA, SAS and XFI. The DS320PR410 heavy driver features 160mW/channel low active power, 100ps ultra-low latency and -10dB return loss at 16GHz. These drivers operate from a single 3.3V supply voltage and a -40°C to 85°C temperature range. DS320PR410 redriver is widely used in rack servers, high-performance computing, network-attached storage, network cards, active cables, desktop PCs, hardware accelerators and other fields.

The single channels of the DS320PR410 heavy driver work independently, and each channel includes a continuous-time linear equalizer (CTLE) and a linear output driver. These redrivers can be configured in pin mode, SMBus/I(2)C master mode, and SMBus/I(2)C slave mode. The DS320PR410 redriver does not require a heat sink and is available in a 4mm x 6mm, 40-pin WQFN package.
