DATASHEET 9DB401C Four Output Differential Buffer for PCI Express Description Features/Benefits 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 (50ps), low output-to-output skew (100ps), 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 200MHz in PLL mode or 0 to 400Mhz 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. • 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. Key Specifications • • • • • • Outputs cycle-cycle jitter: < 50ps Outputs skew: < 50ps Extended frequency range in bypass mode: Revision B: up to 333.33MHz Revision C: up to 400MHz Real-time PLL lock detect output pin 28-pin SSOP/TSSOP package Available in RoHS compliant packaging Output Features • • • 4 - 0.7V HCSL or LVDS differential output pairs Supports zero delay buffer mode and fanout mode Bandwidth programming available Functional Block Diagram OE (1,6) 2 Spread Compatible PLL -SRC_IN -SRC_IN# M U X Stop Logic 4 DIF (1,2,5,6) -PD -BYPASS#/PLL -SDATA Control Logic -SCLK IREF Note: Polarities shown for OE_INV = 0.

PD# must be asserted before shutting off the input clock or power to insure an orderly shutdown. PD is asynchronous active-low input for both powering down the device and powering up the device. When PD# is asserted, all clocks will be driven high, or tri-stated (depending on the PD# drive mode and Output control bits) before the PLL is shut down. PD# Assertion When PD# is sampled low by two consecutive rising edges of DIF#, all DIF outputs must be held High, or tri-stated (depending on the PD# drive mode and Output control bits) on the next High-Low transition of the DIF# outputs. When the PD# drive mode bit is set to ‘0’, all clock outputs will be held with DIF driven High with 2 x IREF and DIF# tri-stated. If the PD# drive mode bit is set to ‘1’, both DIF and DIF# are tri-stated. PWRDWN# DIF DIF# PD# De-assertion Power-up latency is less than 1 ms. This is the time from de-assertion of the PD# pin, or VDD reaching 3.3V, or the time from valid SRC_IN clocks until the time that stable clocks are output from the device (PLL Locked).
