• Manufacturer Part Number: pck3807a
• Description: 1 10 Lvttl Clock Distribution Device
• Manufacturer: NXP Semiconductors

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.
