CGS74B2525
1-to-8 Minimum Skew Clock Driver
General Description
This minimum skew clock driveris designedfor Clock Gen-
eration and Support (CGS) applications operating well
above20 MHz(33 MHz,50 MHz). The device guarantees
minimum output skew acrossthe outputsofa given device
and also from device-to-device. Skew parametersare also
providedas ameansto measure duty cycle requirementsas
those foundin high speed clocking systems. The ’B2525is minimum skew clock driver with one input driving eight
outputs specifically designedfor signal generationand clock
distribution applications.
