• Features integrated on-chip decoupling for optimized performance and cost reduction
• Designed as a limiting TIA for high-speed serial data systems

Applications

• PON systems
• 10GBASE-SR modules
• High-performance optical receivers

Procurement Notes

Verify the specific ordering suffix DTF8SR against official Semtech documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements and interface standards before procurement.

Selection Notes

Select this component for designs requiring a 10Gbps limiting TIA with a 3.3V supply. Consider its 2.35 kΩ gain and 7 GHz bandwidth for matching photodiode interfaces in PON or SR applications.

Part Context

Semtech offers a comprehensive portfolio of optical transceiver ICs and components for various Ethernet, CPRI, and SONET/SDH standards. The NT28L52 belongs to their line of TIAs, which provide wideband, low-noise pre-amplification for PIN photodiodes or APDs.

Replacement Considerations

Consult official Semtech documentation for verified substitute part numbers. Do not assume cross-compatibility with other TIA models without verifying pinout and electrical parameter alignment.
