What are the key features of TLK2541PFPRG4?
- 1 Gbps to 2.6 Gbps SerDes engine optimized for EPON OLT applications requiring high-throughput optical line card design
- 80-pin TQFP package with integrated heat slug supports 260°C peak reflow for standard SMT manufacturing
- Single-function PCS architecture reduces external glue logic and simplifies EPON MAC-to-PHY interface routing
- Pb-free JESD-609 e4 compliant construction meets RoHS requirements for telecom equipment compliance
What is TLK2541PFPRG4 used for?
The TLK2541PFPRG4 is designed for EPON Optical Line Terminal line cards in fiber-to-the-home (FTTH) access networks, where 1 Gbps to 2.6 Gbps serial data rates between the MAC and the optical module are required. It is also used in passive optical network central office equipment, metro Ethernet switches, and high-density line card aggregation platforms that demand reliable SerDes at 2.6 Gbps. The 80-pin TQFP form factor suits board designs where controlled-impedance routing and fine-pitch SMT placement are standard practice.

Frequently Asked Questions
What data rate range does the TLK2541PFPRG4 SerDes support in EPON OLT line card designs?
The TLK2541PFPRG4 supports serial data rates from 1 Gbps to 2.6 Gbps, covering both standard EPON downstream and upstream burst rates. This range makes it compatible with EPON MAC chipsets that interface to 1.25 Gbps or 2.5 Gbps optical modules in fiber-to-the-home access deployments.
Which package does the TLK2541PFPRG4 use, and how does it affect PCB thermal management?
The TLK2541PFPRG4 uses an 80-pin TQFP package with an integrated heat sink slug rated for 260°C peak reflow temperature. The exposed thermal pad improves heat dissipation on the PCB, making it suitable for high-density EPON OLT line cards where junction temperature management is critical at 2.6 Gbps operation.
When would a system designer choose TLK2541PFPRG4 over a discrete multi-chip SerDes and CDR solution?
Designers targeting compact EPON OLT cards at 1 Gbps to 2.6 Gbps benefit from TLK2541PFPRG4 because its integrated PCS and SerDes engine eliminate a separate clock-data recovery IC, reducing BOM count, PCB routing complexity, and power consumption compared to a discrete 2-chip SerDes plus CDR approach in an 80-pin footprint.
Is TLK2541PFPRG4 compliant with RoHS and lead-free assembly requirements for telecom equipment?
Yes, TLK2541PFPRG4 carries the Pb-free code and meets JESD-609 e4 classification, confirming compatibility with lead-free solder paste and 260°C peak reflow profiles. This satisfies RoHS directive requirements for telecom and networking equipment sold in the EU and other regulated markets.
