Product data sheet
PCK3807A
DESCRIPTION
This low skew clock driver offers 1:10 fan-out. The large fan out from
a single input reduces loading on the preceding driver and provides
an efficient clock distribution network. The PCK3807A offers low
capacitance inputs with hysteresis for improved noise margins.
Multiple power and grounds reduce noise. Typical applications are
clock and signal distribution.
The PCK3807A operates from a single 2.5 V or 3.3 V supply voltage
and over the full industrial temperature range of –40 °C to +85 °C.
FEATURES
• Low output skew < 120 ps (max)
• Very low duty cycle distortion < 200 ps (max) for V_CC = 2.5 V
