10 Power Supply Recommendations

There are two power supplies in SN65LVDS4, VCC which is the core power supply and VDD which is the output drive power supply. For proper device operation it is recommended that VCC should be powered up first and then VDD or VCC applied at the same time as VDD (VCC and VDD tied together). It is also recommended that VCC should be equal to or less than VDD as shown in Table 3.

Table 3. Power Supply Acceptable Combinations

VCC (V) VDD (V) Recommended
1.8 1.8 yes
1.8 2.5 yes
1.8 3.3 yes
2.5 1.8 no
2.5 2.5 yes
2.5 3.3 yes
