Key Features

  • Multi-rate support for OC-12, OC-24, and OC-48 SONET/SDH up to 2.488 Gbps
  • 2.5 V nominal supply voltage enabling low-power optical transport system integration
  • 100-pin fine-pitch PQFP package with heat-slug for thermally demanding environments
  • Single-chip transceiver integrating CDR and framing for reduced BOM complexity

Applications

The SLK2511CPZP is designed for high-speed optical networking equipment including SONET/SDH add-drop multiplexers, digital cross-connects, and OC-48 line cards where multi-rate operation at up to 2.488 Gbps is required. Its 2.5 V supply and integrated CDR function streamline the design of long-haul and metro fiber transmission systems. Telecom infrastructure builders use it to support backward-compatible OC-12 and OC-24 ports alongside OC-48 uplinks on the same hardware platform.

Frequently Asked Questions

Which SONET/SDH data rates does the SLK2511CPZP natively support?

The SLK2511CPZP supports OC-12 (622 Mbps), OC-24 (1.244 Gbps), and OC-48 (2.488 Gbps) line rates, allowing a single chip to serve multi-rate optical transport systems without redesigning the host board.

What supply voltage does the SLK2511CPZP require, and how does it affect power distribution design?

The device operates from a nominal 2.5 V supply, which simplifies power distribution in mixed-voltage line cards while reducing core power dissipation compared to older 3.3 V transceivers operating at similar data rates.

For an OC-48 aggregation shelf, how does the SLK2511CPZP's 100-pin PQFP package influence board layout?

The 100-pin PQFP with fine-pitch leads and integrated heat slug requires careful escape routing on a multilayer PCB, but its square flatpack footprint fits standard line-card formats used in 19-inch telecom shelf assemblies.

When is the SLK2511CPZP a preferred choice over a single-rate OC-48 transceiver?

When a platform must provision OC-12, OC-24, and OC-48 tributaries on the same port, the SLK2511CPZP's multi-rate capability eliminates the need for separate single-rate devices, reducing component count and simplifying firmware rate negotiation.
