NBSG14
2.5V/3.3V SiGe Differential
1:4 Clock/Data Driver with
RSECL* Outputs
*Reduced Swing ECL
Description
The NBSG14 is a 1−to−4 clock/data distribution chip, optimized for
ultra−low skew and jitter.
Inputs incorporate internal 50 W termination resistors and accept
NECL (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 Typical
• Maximum Input Data Rate up to 12 Gb/s Typical
• 30 ps Typical Rise and Fall Times
• 125 ps Typical Propagation Delay
• RSPECL Output with Operating Range: VCC = 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

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
*Typicals used for testing purposes.
**The device packaged in FCBGA−16 have maximum temperature specification of 70°C and devices packaged in QFN−16 have maximum
temperature specification of 85°C.
4. Input and output parameters vary 1:1 with VCC. VEE can vary +0.125 V to −0.5 V.
5. All outputs loaded with 50 W to VCC − 1.5 V for BGA package and VCC − 2 V for QFN package. VOH/VOL measured at VIH/VIL (Typical).
6. VIHCMR min varies 1:1 with VEE, VIHCMR max varies 1:1 with VCC. The VIHCMR range is referenced to the most positive side of the differential
input signal.
7. VIH cannot exceed VCC. |VIH − VTHR| < 2600 mV.
8. VIL always ≥ VEE. |VIL − VTHR| < 2600 mV.
9. VTHR is the voltage applied to one input when running in single−ended mode.
