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.
