NB6L56 Datasheet, PDF (1/10 Pages) ON Semiconductor – Dual 2:1 Differential Clock Data Multiplexer

NB6L56
2.5V / 3.3V Dual 2:1
Differential Clock / Data
Multiplexer with LVPECL
Outputs
Multi−Level Inputs w/ Internal Termination
The NB6L56 is a high performance Dual 2−to−1 Differential Clock
or Data multiplexer. The differential inputs incorporate internal 50 W
termination resistors that are accessed through the VT pin. This feature
allows the NB6L56 to accept various Differential logic level
standards, such as LVPECL, CML or LVDS. Outputs are 800 mV
LVPECL signals. For interface options see Figures 12 − 15.
The NB6L56 produces minimal Clock or Data jitter operating up to
2.5 GHz or 2.5 Gbps, respectively. As such, the NB6L56 is ideal for
SONET, GigE, Fiber Channel, Backplane and other Clock/Data
distribution applications.
The NB6L56 is offered in a low profile 5 mm x 5 mm 32−pin QFN
package and is a member of the ECLinPS MAX™ family of high
performance Clock / Data products. Application notes, models, and
support documentation are available at www.onsemi.com.
