DATASHEET
MK2304-2
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.

External Components
The Mk2304-2 requires a minimum number of external components for proper operation. Decoupling capacitors of
0.1µF should be connected between VDD and GND, as close to the part as possible. A 33series terminating
resistor should be used on each clock output to reduce reflections.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the MK2304-2. 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.
