DESCRIPTION
TypicalAPPLICATIONS
● Riser cards● Storage
● Networking
● JBOD Output
FEATURES
● Four 0.7V current-mode differential HCSL output pairs● Supports zero delay buffer (ZDB) mode and fanout mode
● Selectable bandwidth for zero delay mode
● 50–110 MHz operation in PLL mode
● 5–166 MHz operation in Bypass mode
FEATURES
● SPS internal receiver bias network keeps input clock parked when input is floating● Supports both 85Ω and 100Ω output impedance with appropriate resistor selection
● OE# pins default to controlling outputs
● PLL or Bypass mode; PLL can dejitter incoming clock
● Selectable PLL bandwidth; minimizes jitter peaking in downstream PLLs
● Spread spectrum compatible
● Outputs default to Hi-Z when disabled or when device is powered down
● SMBus interface; unused outputs can be disabled
● 3 selectable SMBus addresses Key Specifications
● PCIe Gen3 jitter < 0.6ps rms in ZDB mode
● PCIe Gen4 additive jitter < 0.1ps rms in fanout mode
● Output cycle-to-cycle jitter < 50ps...
