Limiting amplifier for optical receiver front-ends
The ONET1191PRGTR is a limiting amplifier from Texas Instruments designed for optical network applications. It sits in the receiver signal chain after the photodiode and transimpedance amplifier, squaring up the data eye for the downstream clock-and-data recovery (CDR) or decision circuit.
Package and rework — the QFN reality
The 16-VFQFN exposed-pad package is a standard QFN footprint. The exposed pad is the thermal and electrical ground path — it needs a good solder joint to the board's ground plane.
The ROHS3 compliance means it is fully exempt-free and suitable for markets with strict environmental regulations, including EU RoHS.
Sourcing posture — quoted to order
There is no single-source risk — the part is widely stocked across the broker and surplus market. For a production run or a prototype build, submit an RFQ to lock in the price and lead time for your quantity.
