Note 2: The charge pump on the MAX3171/MAX3173 can supply V+ and V- to the MAX3172/MAX3174. The V+ and V- input levels
vary with the mode of chipset operation as follows:
V.35/V.28 modes: +5.55V ≤ V+ ≤ +6.50V, -6.50V ≤ V- ≤ -5.45V
Typical operation: V+ = +5.90V, V- = -5.80V
V.10/V.11 modes: +4.20V ≤ V+ ≤ +5.0V, -4.60V ≤ V- ≤ -3.80V
Typical operation: V+ = +4.60V, V- = -4.20V
The MAX3171/MAX3173 are guaranteed to provide these V+/V- supply levels.
