PRELIMINARY DATASHEET  
LOW SKEW 1 TO 4 CLOCK BUFFER  
5P30001  
Description  
Features  
The 5P30001 is a low skew, single input to four output,  
clock buffer. Part of IDT’s ClockBlocks family, this is our  
lowest skew, small clock buffer.  
Extremely low skew outputs (50 ps)  
Packaged in 8-pin DFN  
TM  
RoHS compliant packaging  
Low power CMOS technology  
Operating Voltages of 1.2 to 2.5 V  
Output Enable pin tri-states outputs  
3.3 V tolerant input clock  
IDT makes many non-PLL and PLL based low skew output  
devices as well as Zero Delay Buffers to synchronize  
clocks. Contact us for all of your clocking needs.

Input  
Output Enable. Tri-states outputs when low. Connect to VDD for normal operation.  
External Components  
A minimum number of external components are required for proper operation. A decoupling capacitor of 0.01 µF  
should be connected between VDD on pin 1 and GND on pin 4, as close to the device as possible. A 33 series  
terminating resistor may be used on each clock output if the trace is longer than 1 inch.  
To achieve the low output skew that the 5P30001 is capable of, careful attention must be paid to board layout.  
Essentially, all 4 outputs must have identical terminations, identical loads and identical trace geometries. If they do  
not, the output skew will be degraded. For example, using a 30series termination on one output (with 33on the  
others) will cause at least 15ps of skew.

Absolute Maximum Ratings  
Stresses above the ratings listed below can cause permanent damage to the 5P30001. These ratings, which are  
standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these  
or any other conditions above those indicated in the operational sections of the specifications is not implied.  
Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical  
parameters are guaranteed only over the recommended operating temperature range.
