RENESAS 9DB108BFLFT

ICS9DB108 follows the Intel DB400 Differential Buffer Specification. This buffer provides four SRC clocks for PCI-Express, next generation I/O devices. ICS9DB108 is driven by a differential input pair from a CK409/CK410 main clock generator, such as the ICS952601 or ICS954101. ICS9DB108 can run at speeds up to 200MHz. It provides outputs meeting tight cycle-to-cycle jitter (50ps) and output-to-output skew (50ps) requirements.

• 8 * 0.7V current-mode differential output pairs
• Supports zero delay buffer mode and fanout mode
• Bandwidth programming available
• Outputs cycle-cycle jitter <50ps
• Outputs skew: 50ps +/- 300ppm frequency accuracy on output clocks
• Supports tight ppm accuracy clocks for Serial-ATA
• Spread spectrum modulation tolerant, 0 to -0.5% down spread and +/- 0.25% center spread
• Supports undriven differential output pair in PD# and SRC_STOP# for power management
