bandgap voltage and bias generation
The ONET3301PA limiting amplifier is supplied by a single 3.3-V
±
10% supply voltage connected to the VCC
and VCCO pins. This voltage is referred to ground (GND).
An on-chip bandgap voltage circuitry generates a supply voltage independent reference from which all other
internally required voltages and bias currents are derived.
package
For the ONET3301PA, a small footprint 3 mm
×
3 mm 16-pin QFN package is used with a lead pitch of 0,5 mm.
The pin out is shown in Figure 2.

LOS threshold adjustment with resistor to GND.
Disables CML output stage when set to high level.
High level indicates that the input signal amplitude is below the programmed threshold level.
Circuit ground. Exposed die pad (EP) must be grounded.
Output data signal polarity select (internally pulled up): Setting to high level or leaving pin open selects
normal polarity. Low level selects inverted polarity.
