Product Description

The PI6C49X0210-A is a high performance multi-voltage 10-outputs CMOS Fanout Buffer with internal Crystal Oscillator. The XTAL range is from 10MHz to 50MHz. The device has a wide range of operating voltages of 2.5V and 3.3V. The device also provides user selectable output VDD option, which provides excellent flexibilities to users. This device is ideal for systems that need to distribute low jitter clock signals to multiple destinations.


  • 10 single-ended outputs Fanout Buffer
  • Up to 200MHz output frequency
  • Ultra low output additive jitter = 0.05ps (typ.)
  • Selectable reference inputs support Xtal (10~50MHz), single ended and differential
  • Low output skew ~ 50ps (typ.)
  • Propagation delay ~2ns (typ@3.3V)
  • 2.5V / 3.3V operation
  • User configurable output VDD in different banks:
    – Mixed 3.3V core/2.5V output operating supply
    – Mixed 3.3V core/1.8V output operating supply
    – Mixed 3.3V core/1.5V output operating supply
    – Mixed 2.5V core/1.8V output operating supply
    – Mixed 2.5V core/1.5V output operating supply
  • Industrial temperature range: –40°C to +85°C
  • Packaging (Pb-free & Green available):
    – 32-pin TQFN (ZH)


  • Networking systems including switches and Routers
