2.4 DC Electrical Characteristics

This section describes the DC electrical characteristics for the MSC8103. The measurements in Table 2-4 assume

the following system conditions:

•TJ = 0 – 100 °C

• VDD = 1.6 V ± 5% VDC

• VDDH = 3.3 V ± 5% VDC

• GND = 0 VDC

Note:

The leakage current is measured for nominal VDDH and VDD or both VDDH and VDD must vary in the same

direction (for example, both VDDH and VDD vary by ± 5 percent).

Notes:

See Figure 2-1 for undershoot and overshoot voltages.

The optimum CLKIN duty cycle is obtained when: VILC = VDDH – VIHC.

Not tested. Guaranteed by design.
