General Description 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.

PD# The PD# pin cleanly shuts off all clocks and places the device into a power saving mode. 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). If the PD# drive mode bit is set to ‘1’, all the DIF outputs must driven to a voltage of >200 mV within 300 ms of PD# de-assertion. Tstable 200 mV) within 10 ns of de-assertion.
