PI6CL10804
1.2V/1.5V, 200MHz, 1:4 Networking Clock Buffer
Features
Description
• High-speed, low-noise, non-inverting 1:4 buffer
The PI6CL10804 is a 1.2V or 1.5V high-speed, low-noise
1:4 non-inverting clock buffer. The key goal in designing the
PI6CL10804 is to target networking applications that require
low-skew, low-jitter, and high-frequency clock distribution.
• Maximum Frequency up to 200 MHz
• Low output skew < 100ps
• Low propagation delay < 3.5ns
Providing output-to-output skew as low as 100ps, the PI6CL10804
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.
• Optimized duty cycle
• 3.3V tolerent input
• 1.2V or 1.5V supply voltage
• Packages (Pb-free & Green available):
