Overview
Low Skew 1 to 4 Clock Buffer 524S DATASHEET Description The 524S is a low skew, single input to four output, clock buffer.
The 524S has best in class additive phase jitter of sub 50 fsec.
The 524S is Power Down Tolerant (PDT).
PDT designated inputs may be driven before VDD is applied, without damage to the device.
Renesas makes many non-PLL and PLL based low skew output devices as well as Zero Delay Buffers to synchronize clocks.

External Components A minimum number of external components are required for proper operation.
A decoupling capacitor of 0.
01µF should be connected between VDD on pin 5 and GND on pin 8, 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 524S is capable of, careful attention must be paid to board layou...
