MK2308-2
ZERO DELAY, LOW SKEW BUFFER
Description
The MK2308-2 is a low jitter, low skew, high
performance Phase-Lock Loop (PLL) based zero delay
buffer for high speed applications. Based on ICS’
proprietary low jitter PLL techniques, the device
provides eight low skew outputs at speeds up to 160
MHz at 3.3 V. The MK2308-2 includes a bank of four
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 eight outputs. Compared to competitive
CMOS devices, the MK2308-2 has the lowest jitter.
Features
