• Manufacturer Part Number: ics9db104
• Description: Four Output Differential Buffer For Pci-express
• Manufacturer: Integrated Device Technology

ICS9DB104 follows the Intel DB400 Differential Buffer Specification. This buffer provides four SRC clocks for PCI-Express,
next generation I/O devices. ICS9DB104 is driven by a differential input pair from a CK409/CK410 main clock generator, such
as the ICS952601 or ICS954101. ICS9DB104 can run at speeds up to 200MHz. It provides ouputs meeting tight cycle-to-cycle
jitter (50ps) and output-to-output skew (50ps) requirements.
