PCS2P20807A September 2006 rev 0.3 2.5V CMOS 1-TO-10 CLOCK DRIVER Features Product Description • 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 PCS20807A is an ideal clock distribution device for • TTL compatible inputs and outputs synchronous systems. Multiple power and grounds reduce • 1:10 fanout noise. Typical applications are clock and signal distribution. • Maximum output rise and fall time < 1.25nS (max.) • Low input capacitance: 3pF (typ) • 2.5V Supply Voltage • Available in SSOP and QSOP Packages 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.
