A product Line of Diodes Incorporated PI6C49X0210-A High Performance 1:10 Multi-Voltage CMOS Buffer Features Applications 10 single-ended outputs Fanout Buffer Networking systems including switches and Routers Up to 200MHz output frequency High frequency backplane based computing and telecom Ultra low output additive jitter = 0.05ps (typ.) platforms Selectable reference inputs support Xtal (10~50MHz), single- ended and differential Description Low output skew ~ 50ps (typ.) The PI6C49X0210-A is a high performance multi-voltage 10-outputs Propagation delay ~2ns (typ 3.3V) CMOS Fanout Buffer with internal Crystal Oscillator. The XTAL 2.5V / 3.3V operation range is from 10MHz to 50MHz. The device has a wide range of User configurable output VDD in different banks: operating voltages of 2.5V and 3.3V. The device also provides user Mixed 3.3V core/2.5V output operating supply selectable output VDD option, which provides excellent flexibilities Mixed 3.3V core/1.8V output operating supply to users. This device is ideal for systems that need to distribute low Mixed 3.3V core/1.5V output operating supply jitter clock signals to multiple destinations.
