Diodes Incorporated has introduced a ReDriver for the server, storage, and networking market segment.
The company’s PI3EQX16904GL is a PCIe 4.0 compliant, 2.5Gbps to 16Gbps, four-differential channel, linear ReDriver which provides programmable linear equalization, output swing, and flat gain to optimize performance over a variety of physical media by reducing inter-symbol interference.
Diodes said that it is the industry’s first available ReDriver to support PCIe 4.0 while being backward-compatible with PCIe 3.0/2.0/1.0.
The Key Application for the device includes:
Also known as a repeater IC, the ReDriver regenerates signals to boost the signal quality of high-speed interfaces. Faster signal frequencies leave designers with less signal margin with which to design reliable, high-performance systems. Using equalization, pre-emphasis, and other technologies, a single ReDriver can adjust and correct for known channel losses at the transmitter and restore signal integrity at the receiver. This enables reliable communications with low bit error rates (BER).
The device supports four 100Ω differential current mode logic (CML) data I/Os and extends the signals across other distant data pathways on the user’s platform. Linear ReDrivers are commonly used to achieve PCB trace extension while minimizing cost and power consumption. They can also deliver lower latency.
Requiring a supply voltage of 3.3V ±0.3V, the device is able to operate over an industrial temperature range of -40°C to +85°C.
The PI3EQX16904GL ReDriver is offered in a 42-contact TQFN (9mm x 3.5mm) package.
