The 9DB401C is a DB400 Version 2.0 Yellow Cover part with PCI Express® support. It can be used in PC or embedded systems to provide outputs that have low cycle-to-cycle jitter (50 ps), low output-to-output skew (100 ps), and are PCI Express® gen 1 compliant. The 9DB401C supports a 1 to 4 output configuration, taking a spread or non spread differential HCSL input from a CK410(B) main clock such as 954101 and 932S401, or any other differential HCSL pair. 9DB401C can generate HCSL or LVDS outputs from 50 to 200 MHz in PLL mode or 0 to 400 MHz in bypass mode. There are two de-jittering modes available selectable through the HIGH_BW# input pin, high bandwidth mode provides de-jittering for spread inputs and low bandwidth mode provides extra de-jittering for non-spread inputs. The SRC_STOP#, PD#, and OE real-time input pins provide completely programmable power management control.


  • 4 - 0.7 V HCSL or LVDS differential output pairs
  • Supports zero delay buffer mode and fanout mode
  • Bandwidth programming available
  • Spread spectrum modulation tolerant, 0 to -0.5% down spread and +/- 0.25% center spread
  • Supports undriven differential outputs in PD# and SRC_STOP# modes for power management.
  • Outputs cycle-cycle jitter: < 50 ps
  • Outputs skew: < 50 ps
  • Extended frequency range in bypass mode: Revision B: up to 333.33 MHz Revision C: up to 400 MHz
  • Real-time PLL lock detect output pin
  • 28-pin SSOP/TSSOP package
  • Available in RoHS compliant packaging
