IDT™
ZERO DELAY, LOW SKEW BUFFER 1
MK2304-2 REV G 051310
Description
The MK2304-2 is a low jitter, low skew, high performance
Phase Lock Loop (PLL) based zero delay buffer for high
speed applications. Based on IDT’s proprietary low jitter
PLL techniques, the device provides four low skew outputs
at speeds up to 133 MHz at 3.3 V. The MK2304-2 includes
a bank of two outputs running at 1/2X. In the zero delay
mode, the rising edge of the input clock is aligned with the
rising edges of all 4 outputs. Compared to competitive
CMOS devices, the MK2304-2 has the lowest jitter.
The MK2304-2 PLL enters a power-down state when there
are no rising edges on the REF input. In this mode, all
outputs are tri-stated and the PLL is turned off, resulting in
leass than 25 µA of current draw.
IDT manufactures the largest variety of clock generators
and buffers and is the largest clock supplier in the world.
