1 Features High-speed, low-noise, non-inverting 1:4 buffer Maximum Frequency up to 200 MHz Low output skew < 100ps Low propagation delay < 3.5ns Optimized duty cycle 3.3 tolerent input 1.2 or 1.5 supply voltage Packages (Pb-free & Green available): -8-pin SOIC (W) Description The PI6CL10804 is a 1.2 or 1.5 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. 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.

Note: Storage Temperature C to +150 C DD oltage to +2.6 Output oltage (max. 3.6) to DD +0.5 Input oltage to 3.6 Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 1.5 DC Characteristics (Over Operating Range: DD = 1.5 ± 0.1, T A = -40 to 85 C) Parameters Description Test Conditions (1) Min.
