Timing Zoom
The 12.5 GHz timing zoom with 256 K sample memory gives you simultaneous state and high-
resolution timing measurements covering a time span of 20 us, which corresponds to 43680
clock cycles at a 2133 MHz clock rate. Timing zoom also provides simultaneous high-resolution
timing measurements with conventional and transitional timing modes of operation.
Figure 3. Timing zoom can be used to measure the time between the rising edge of the clock and the rising
edge of DQS in a DDR system.
