Description
The PI6C49X0208 is a high performance multi-voltage 8-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 exibilities
to users. This device is ideal for systems that need to distribute low
jitter clock signals to multiple destinations.
Features
• 8 single-ended outputs Fanout Buffer
• Up to 200MHz output frequency
• Ultra low output additive jitter = 0.01ps (typ.)
• Selectable reference inputs support Xtal (10~50MHz), single-
ended and differential
• Low output skew ~ 50ps (typ.)
• 2.5V / 3.3V operation
• User congurable output VDDO in different banks:
– Mixed 3.3V core, 2.5V, 1.8V or 1.5V output operating
supply
– Mixed 2.5V core, 1.8V, 1.5V or 1.2V output operating
supply
• Industrial temperature range: –40°C to +85°C
• Packaging (Pb-free & Green available):
– 32-pin TQFN (ZH)
Applications
• Networking systems including switches and Routers
• High frequency backplane based computing and telecom
platforms
