PI6C10807
1.8V/2.5V, 250MHz, 1:10 Networking Clock Buffer
Features
Description
• High-speed, low-noise, non-inverting 1-10 buffer
The PI6C10807 is a 1.8V, or 2.5V high-speed, low-noise
1-10 non-inverting clock buffer. The key goal in designing the
PI6C10807 is to target networking applications that require lowskew, low-jitter, and high-frequency clock distribution.
• Maximum Frequency up to 250 MHz
• Low output skew < 60ps
• Low duty cycle distortion < 200ps
Providing output-to-output skew as low as 60ps, the PI6C10807
is an ideal clock distribution device for synchronous systems. Designing synchronous networking systems requires a tight level of
skew from a large number of outputs.
• Low propagation delay < 2.0ns
• Multiple VDD, GND pins for noise reduction
• 1.8V or 2.5V supply voltage
• Packages (Pb-free & Green):
▫20-pin, TSSOP (L20)
▫20-pin, SSOP (H20)
