9DBL0243

2-Output 3.3V LP-HCSL Zero-Delay 9DBL0243 / 9DBL0253 Buffer with LOS Indicator Datasheet Description The 9DBL0243 / 9DBL0253 devices are 3.3V members of IDT's Full-Featured PCIe clock family. They support PCIe Gen1–4 Common Clock (CC) architectures and also support NVLINK applications. The 9DBL0243 / 9DBL0253 parts have a Loss of Signal (LOS) indicator to support fault-tolerant, high-reliability systems. Typical Applications ▪ PCIe Gen1–4 and NVLINK clock distribution for Riser Cards ▪ Storage and Networking ▪ JBOD ▪ Communications ▪ Access Points Output Features ▪ Loss Of Signal (LOS) open drain output ▪ 2 1–200 MHz Low-Power (LP) HCSL DIF pairs — 9DBL0243 default Zout = 100Ω — 9DBL0253 default Zout = 85Ω ▪ Easy AC-coupling to other logic families; see IDT application note AN-891. Key Specifications ▪ PCIe Gen1–4 CC compliant in ZDB or fanout buffer mode ▪ Supports NVLINK at 156.25MHz in ZDB or fanout buffer mode ▪ DIF cycle-to-cycle jitter < 5...
