1:10 LVTTL clock distribution device

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

= 2.5 V

CC

•High speed: propagation delay < 3.5 ns (max)

•Very low CMOS power levels

•TTL compatible inputs and outputs

•1:10 fanout

•Maximum output rise and fall times < 1.5 ns

•Low input capacitance: 2.5 pF typical

•V

= 2.3 V to 3.6 V

CC

•Overvoltage tolerance on inputs

•Available in SSOP, TSSOP, SO and QSOP packages

•>150 MHz operation
