Industry’s first PCI Express 8-Gbit/s quad equalizer
Device extends backplane and cable reach, while consuming only 100-mW per channel
Designed for PCI Express (PCIe) applications up to 8 Gbit/s data transmission rates, the DS50EV401 quad equalizer is offered as the first of its kind, while consuming only 100 mW per channel. The device supports PCIe Gen1 (2.5 Gbit/s), PCIe Gen2 (5 Gbit/s) and PCIe Gen3 (8 Gbit/s) data rates.
The quad equalizer compensates for transmission medium losses, reducing deterministic jitter on four data transmission channels. It provides 20 dB of receive boost to equalize up to 10 m of PCIe cable or 40 in. of FR-4 printed circuit board at data transmission rates up to 5 Gbit/s, with less than 0.2 unit intervals (UI) of residual jitter at the equalizer output.
Additionally, the device equalizes up to 30 in. of FR-4 at data rates up to 8 Gbit/s, while maintaining the same jitter performance. Housed in a 48-pin LLP package, it uses differential CML inputs and outputs that feature 8 kV of ESD protection. Additionally, the equalizer includes a loss-of-signal detect for each channel, operates over the full -40 to 85C temperature range and requires a single supply voltage of 2.5 or 3.3V.
