DS160PT801ACBR

Signal Buffers, Repeaters, Splitters Overview

The DS160PT801ACBR is an eight-lane (16-channel) protocol-aware PCI Express retimer supporting data rates up to 16.0 GT/s. It operates on dual power supplies of 1.17 V and 1.8 V within an industrial temperature range of −40°C to 85°C. The device utilizes a 332-pin FCCSP package measuring 8.50 mm × 13.40 mm. It supports PCIe Gen-4, Gen-3, Gen-2, and Gen-1 interfaces with adaptive CTLE and DFE equalization. Configuration is managed via SMBus at speeds up to 1 MHz, allowing initial setup from external EEPROM.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ACBR against the manufacturer's current orderable addendum to confirm the large tape-and-reel carrier quantity and lead finish specifications. Ensure that the design environment accommodates the specified moisture sensitivity level and peak reflow temperature requirements during assembly.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending reach for complex multi-connector system topologies or chip-to-chip motherboard links requiring protocol awareness. Evaluate the need for inter-chip communication features if link width scaling beyond eight lanes is required in the final system design.

Signal Buffers, Repeaters, Splitters Part Context
