IDT74FCT20807
FEATURES:
• High frequency > 150MHz
• Guaranteed low skew < 150ps (max.) between any two outputs
• Very low duty cycle distortion < 300ps
• High speed: propagation delay < 3ns
• Very low CMOS power levels
• TTL compatible inputs and outputs
• 1:10 fanout
• Maximum output rise and fall time < 1.25ns (max.)
• Low input capacitance: 3pF typical
• 2.5V supply voltage
• Available in SSOP and QSOP packages
DESCRIPTION:
The FCT20807 is a 2.5V compatible, high speed, low noise, 1:10 fanout,
non-invertingclockbuffer. Thelargefanoutfromasingleinputreducesloading
on the preceding driver and provides an efficient clock distribution network.
Providing output to output skew as low as 150ps, the FCT20807 is an ideal clock
distribution device for synchronous systems. Multiple power and grounds
reduce noise. Typical applications are clock and signal distribution.
