Note 1:
Note 2:
Note 3:
Dice are tested at TA = +27°C.
Minimum voltage at IBIAS = VCC - 1.6V.
The sum of the currents flowing into VCC and PULLUP with RBIASSET = RMODSET = RAPCSET = 2kΩ, IN+ = 1.82V,
IN- = 2.14V.
Note 4: APC is connected to BIASSET for closed-loop operation.
Note 5: Bias current range is guaranteed by the IBIASSET to IBIAS gain test.
Note 6: RPULL-UP is connected between IMOD and PULLUP.
Note 7: VREF is the voltage on BIASSET, MODSET, or APCSET with RBIASSET = RMODSET = RAPCSET = 2kΩ.
Note 8: APC is disconnected from BIASSET for open-loop operation.
Note 9: Bias current stability is guaranteed by design and characterization.
Note 10: IQMOD is the current flowing into the collector of QMOD (Figure 1).
Note 11: AC parameters are guaranteed by design and characterization.
Note 12: Modulation current range is guaranteed by the IMODSET to IQMOD gain test.
Note 13: Input signal is a 155Mbps 1-0 pattern. PWD = [(width of wider pulse) - (width of narrower pulse)] / 2.
