NB3L553
2.5 V / 3.3 V / 5.0 V
1:4 Clock Fanout Buffer
Description
The NB3L553 is a low skew 1−to 4 clock fanout buffer, designed for
clock distribution in mind. The NB3L553 specifically guarantees low
output−to−output skew. Optimal design, layout and processing
minimize skew within a device and from device to device.
Features
• Input/Output Clock Frequency up to 200 MHz
• Low Skew Outputs (35 ps), Typical
• RMS Phase Jitter (12 kHz – 20 MHz): 29 fs (Typical)
• Output goes to Three−State Mode via OE
• Operating Range: V
DD
= 2.375 V to 5.25 V
• 5 V Tolerant Input Clock I

• Ideal for Networking Clocks
• Packaged in 8−pin SOIC
• Industrial Temperature Range
• These are Pb−Free Devices

for normal operation. Pin has no internal pullup or pull down resistor for open
condition default. Use from 1 to 10 kOhms external resistor to force an open con-
dition default state.
− EP Thermal Exposed Pad (DFN8 only) Thermal exposed pad must be connected to a sufficient thermal
conduit. Electrically connect to the most negative supply (GND) or leave uncon-
nected, floating open.
