932S421BGLFT

932S421BGLFT is a PCIe Gen2 and QPI clock for intel-based server. It is a main clock synthesizer for CK410B-generation Intel server platforms. This is driven with a 14.318MHz crystal. It generates CPU outputs up to 400MHz and PCI-Express clocks at 100. The 48 MHz USB clock is an exact 48.000MHz clock. This generates all other clocks with less the +/- 100ppm error. PCIe Gen 2 and QPI compliant CK410B+ clock for Intel-based servers application.

• Supports spread spectrum modulation, 0 to -0.5% down spread
• Uses external 14.318MHz crystal and external load capacitors for low ppm synthesis error
• CPU clocks independent of SRC/PCI clocks
• D2/D3 SMBus address
• PCIe Gen 2 compliant SRC outputs, QPI and FBD 2 compliant CPU clocks
• CPU cycle-cycle jitter is <lt/> 50ps, SRC cycle-cycle jitter is <lt/> 125ps
• PCI cycle-cycle jitter is <lt/> 500ps, CPU output skew is <lt/> 50ps
• SRC output skew is <lt/> 250ps, ±100ppm frequency accuracy on all outputs
• Powerdown current is 70mA (all diff pairs driven, typ)
• 56-pin TSSOP package, temperature range from 0 to +70°C
