SFP Controller with Dual LDD Interface

NONVOLATILE MEMORY CHARACTERISTICS

= +2.85V to +3.9V, unless otherwise noted.)

Note 1: All voltages are referenced to ground. Current into the IC is positive, and current out of the IC is negative.

Note 2: Inputs are at supply rail. Outputs are not loaded.

Note 3: This parameter is guaranteed by design.

Note 4: Full scale is user programmable.

Note 5: A temperature conversion is completed and MOD1 DAC, MOD2 DAC, APC1 DAC, and APC2 DAC values are recalled

from the LUT and V
