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 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.
Mixed 2.5V core/1.8V output operating supply
Mixed 2.5V core/1.5V output operating supply
Industrial temperature range: 40C to +85C
Packaging (Pb-free & Green available):
32-pin TQFN (ZH)
