PI6C10804
1.5V/1.8V/2.5V, 180MHz, 1:4 Networking Clock Buffer
Features
Description
• High-speed, low-noise, non-inverting 1:4 buffer
The PI6C10804 is a 1.5V to 2.5V high-speed, low-noise
1:4 non-inverting clock buffer. The key goal in designing the
PI6C10804 is to target networking applications that require low-
• Maximum Frequency up to 180 MHz
• Low output skew < 70ps (1.8V, 2.5V), <100ps (1.5V)
• Low propagation delay < 3.0ns (1.8V, 2.5V), <3.5ns (1.5V)
• Optimized duty cycle
skew, low-jitter, and high-frequency clock distribution.
Providing output-to-output skew as low as 70ps, the PI6C10804
is an ideal clock distribution device for synchronous systems. De-
signing synchronous networking systems requires a tight level of
skew from a large number of outputs.
• 1.5V - 2.5V supply voltage
• 3.3V Tolerant input clock
• Packages (Pb-free & Green available):
