NOTE:

4. Standard Measurement Conditions and Description: VDD = 5.0V, VREF = 2.0V, R = 200Ω, 16R - 3.3kΩ, TA = 25oC. The temperature

characteristics of external input data in Figure 10 = all “0” and “1” of rectangular wave; clock frequency = 80MHz.

GE (Glitch Energy)

GE, as described in the HI2315, is a spike noise which

appears synchronizing with the clock falling edge when the

input data (for 1 to 1024 input) changes to 128, 256, 384,

512, 640, 768, 896, and 1024. Figure 11 shows the change

state of GE for the staircase wave output, and Figure 12

shows the repetitive output waveform where the GE

appears. These figures exhibit the difference of this IC from

the convention device.

The HI2315 reduces the GE as shown in Figures 11 and 12.
