9ZXL0832E Datasheet 6 To 12-output Buffers

Manufacturer: Renesas

Overview: 9ZXL06x2E/9ZXL08xxE/9ZXL12x2E 6 to 12-Output Buffers for PCIe Gen1–5 and UPI with SMBus Write Protect Datasheet The 9ZXL revision E family of Zero-Delay/Fanout Buffers (ZDB, FOB) with SMBus Write Protect are 2nd-generation enhanced performance buffers for PCIe and CPU applications. The devices have hardware SMBUS write protection to prevent accidental writes. The family meets all published QPI/UPI, DB2000Q and PCIe Gen1–5 jitter specifications. Devices range from 6 to 12 outputs, with each output having an OE# pin to support the PCIe CLKREQ# function for low power states. All devices meet DB2000Q, DB1200ZL and DB800ZL jitter and skew requirements. Applications ▪ Servers/High-performance Computing ▪ nVME Storage ▪ Networking ▪ Accelerators ▪ Industrial Control Key Specifications ▪ Fanout Buffer Mode additive phase jitter: • PCIe Gen5 CC, UPI > 20Gb/s < 24fs RMS • DB2000Q additive jitter < 39fs RMS • QPI/UPI 11.4GB/s < 40fs RMS • IF-UPI additive jitter < 70fs RMS ▪ ZDB Mode phase jitter: • PCIe Gen5 CC, UPI > 20Gb/s < 22fs RMS • QPI/UPI 11.

This datasheet includes multiple variants, all published together in a single manufacturer document.
