Gen4 and Gen5-Ready Zero-Delay/Fanout Buffer
Features
• 19 outputs in a 6 mm x 6 mm
package
• 1 to 400 MHz fanout buffer mode
• <200 fs rms PCIe Gen4 ZDB mode
• <100 fs rms 12k-20M additive jitter
@156.25 MHz as fanout buffer
• PCIe jitter cleaner mode
• LP-HCSL outputs
• Multiple SMBus addresses
• SMBus security feature – some
family members
• -40C to +85C temperature range
Benefits
• ~90% margin to PCIe Gen4
(Gen5-ready)
• Cascade 3 buffer levels maintaining
>90% margin to PCIe Gen4
• Direct drive of
85W
loads eliminates
up to 122 mm
2
of resistors
• Up to 90% output power reduction
• Clean marginal Gen3/Gen4 clocks
to Gen4 spec
• Easily use multiple devices in a
system
• System security against malicious
BIOS
