What are the key features of ONET8501PBRGTR?
- Rate-selectable limiting amplifier supports 1.25 Gbps to 11.3 Gbps data rates in a single device, covering SONET OC-3 through OC-192 standards
- High sensitivity with integrated signal detect and loss-of-signal (LOS) outputs simplifies optical receiver link monitoring
- Compact 16-pin QFN package with exposed thermal pad enables low-latency PCB integration in SFP and SFP+ optical transceiver modules
What is ONET8501PBRGTR used for?
ONET8501PBRGTR is used in the receive path of optical transceivers for SFP+, XFP, and fiber channel modules operating up to 11.3 Gbps. It amplifies and reshapes the photodiode transimpedance amplifier output into a clean differential signal for downstream CDR and deserializer stages. Its rate-selectable feature makes it compatible across 1G, 10G Ethernet, and SONET OC-192 line card designs without changing the hardware.

Frequently Asked Questions
What data rate range does ONET8501PBRGTR support and which optical standards does it cover?
ONET8501PBRGTR supports selectable data rates from 1.25 Gbps up to 11.3 Gbps, covering standards including SONET OC-3 at 155 Mbps, Gigabit Ethernet at 1.25 Gbps, SONET OC-192 at 9.95 Gbps, and 10 Gbps Ethernet at 10.3125 Gbps. A single device can serve multiple line-rate applications, reducing the need for separate amplifier variants per data rate.
How does ONET8501PBRGTR integrate into an SFP+ optical receiver signal chain?
In an SFP+ receiver, ONET8501PBRGTR sits between the transimpedance amplifier (TIA) and the clock-data recovery (CDR) IC. It amplifies the 11.3 Gbps TIA output to a full differential LVDS or CML swing, reshapes degraded eye diagrams, and provides a loss-of-signal indicator output to the SFP+ module controller, which can then assert the LOS pin to the host system.
What is the operating temperature range of ONET8501PBRGTR and is it suitable for industrial environments?
ONET8501PBRGTR operates over a commercial temperature range of -40°C to +85°C, making it suitable for industrial and telecom line card environments. The 16-pin QFN package with a peak reflow temperature of 260°C is compatible with standard lead-free SMT assembly processes.
When is ONET8501PBRGTR a better fit than a fixed-rate limiting amplifier in an optical module design?
ONET8501PBRGTR is preferred when a module must support multiple data rate standards on the same hardware platform, such as a multi-rate SFP+ that ships as both 1G and 10G variants. Because it is rate-selectable, the PCB design stays identical across SKUs, reducing qualification effort and lowering inventory complexity compared to maintaining 2 or more fixed-rate amplifier part numbers at 1.25 Gbps and 10 Gbps.
