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 (typ)
• 2.5V Supply Voltage
• Available in SSOP and QSOP Packages Product Description The PCS2P20807A is a 2.5V compatible, high speed, low noise, 1:10 fanout, non-inverting clock buffer. The large fanout from a single input reduces loading on the preceding driver and provides an efficient clock distribution network. Providing output to output skew as low as 150pS, the PCS20807A is an ideal clock distribution device for synchronous systems. Multiple power and grounds reduce noise. Typical applications are clock and signal distribution. Block Diagram O10 IN
