NBSG14: SiGe Clock / Data Fanout Buffer, 1:4 Differential, 2.5 V / 3.3 V, with RSECL Outputs
The NBSG14 is a 1-to-4 clock/data distribution chip, optimized for ultra-low skew and jitter.Inputs incorporate internal 50-ohm termination resistors and acceptNECL (Negative ECL), PECL (Positive ECL), LVTTL, LVCMOS, CML, or LVDS. Outputs are RSECL (Reduced Swing ECL), 400 mV.
Features- Maximum Input Clock Frequency up to 12 GHz
- Maximum Input Data Rate up to 12 Gb/s Typical
- 50 Ω Internal Input Termination Resistors
- 30 ps Typical Rise and Fall Times
- 125 ps Typical Propagation Delay
- RSPECL Output with Operating Range: V = 2.375 V to 3.465 V with VEE = 0 V
- RSNECL Output with RSNECL or NECL Inputs with Operating Range: VCC = 0 V with VEE = -2.375 V to -3.465 V
- RSECL Output Level (400 mV Peak-to-Peak Output),
- Compatible with Existing 2.5 V/3.3 V LVEP, EP, and LVEL Devices
