Signal Buffers, Repeaters, Splitters datasheet and documents for PI3EQX8908A2ZFE

PI3EQX8908A2ZFE

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX8908A2ZFE is an 8-channel PCI Express ReDriver manufactured by Diodes Incorporated. It supports data rates of 2.5 Gbps, 5.0 Gbps, and 8.0 Gbps to comply with PCIe Gen 1, Gen 2, and Gen 3 protocols. The device features eight 100-Ohm differential CML data I/Os and provides programmable linear equalization, output swing, and gain via pin strapping, I2C control, or external EEPROM loading. It operates on a single 3.3V ±0.3V supply voltage within an industrial temperature range of -40°C to +85°C. The component is housed in a 54-contact Very Thin Quad Flat No-Lead (TQFN) package.

Signal Buffers, Repeaters, Splitters Feature Summary
