Product data sheet Rev. 01 — 10 April 2006 6 of 17 Philips Semiconductors PCK9446 2.5 V and 3.3 V LVCMOS clock fan-out buffer 9. Static characteristics [1] The PCK9446 is capable of driving 50 Ω transmission lines on the incident edge. Each output can drive one 50 Ω parallel terminated transmission line to a termination voltage of VT. Alternately, the device drives up to two 50 Ω series terminated transmission lines. [2] Input pull-up/pull-down resistors influence input current. [1] The PCK9446 is capable of driving 50 Ω transmission lines on the incident edge.
