PCS2P2305NZ 3.3V 1:5 Clock Buffer
Features
One-Input to Five-Output Buffer/Driver Buffers all frequencies from DC to 133.33MHz Low power consumption for mobile applications Less than 32mA at 66.6MHz with unloaded outputs Input-Output delay: 6nS(max) Output-output skew less than 250pS 8-pin SOIC Package Supply Voltage: 3.3V 0.3V Commercial and Industrial temperature range
Functional Description
PCS2P2305NZ is a low-cost high-speed buffer designed to accept one clock input and distribute up to five clocks in mobile PC systems and desktop PC systems. The device operates at 3.3V and outputs can run up to 133.33MHz. PCS2P2305NZ is designed for low EMI and power optimization and consumes less than 32mA at 66.6MHz, making it ideal for the low-power requirements of mobile systems. It is available in an 8-pin SOIC Package over Commercial and Industrial temperature range.
