Overview
Description
The 9DB401 follows the Intel DB400 Differential Buffer Specification v2.0. This buffer provides four PCI-Express SRC clocks. The 9DB401 is driven by a differential input pair from a CK409/CK410/CK410M main clock generator, such as the 952601, 954101 or 954201. It provides outputs meeting tight cycle-to-cycle jitter (50 ps) and output-to-output skew (50ps) requirements.
Features
- 4- 0.7 V HCSL differential output pairs
- Phase jitter: PCIe Gen1 < 86 ps peak to peak
- Supports zero delay buffer mode and fanout mode
- Bandwidth programming available
- 50-100 MHz operation in PLL mode
- 50-400 MHz operation in Bypass mode

Tips for Using This Parametric Table:
- Hide Filters button in header: Collapse or expands filters
- Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
- Reset button in header: Reset all filters to the page default
- Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
- Export button in header: Export the filtered results of the table to an Excel document
- Filter parts search bar in header: Type to filter table results by part number
- Hide column button in column headers: Select to hide columns in table
- AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
- Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
