TLK1521IPAP

Overview

The TLK1521IPAP is a WizardLink family serializer/deserializer supporting serial data rates from 500 Mbps to 1.3 Gbps. It interfaces with an 18-bit parallel bus, encoding data into a 20-bit stream using start/stop framing. The device operates on a 2.5-V supply and features a 64-pin HTQFP PowerPAD package. Typical power consumption is 288 mW at 1.3 Gbps. It includes selectable preemphasis for lossy media, internal loopback for testing, and hot-plug protection.

Feature Summary

• Supports high-speed bidirectional point-to-point data transmission over controlled impedance media such as backplanes or copper cables.
• Features selectable signal preemphasis to compensate for inter-symbol interference in lossy transmission lines.
• Provides rapid synchronization via SYNC patterns and supports random lock synchronization for open-loop applications.
• Includes built-in self-test capabilities through an internal loopback path.

Applications

• High-speed backplane interconnect systems
• Point-to-point baseband data transmission links
• Replacing parallel data architectures to reduce trace counts

Procurement Notes

Verify the component matches the Texas Instruments WizardLink series specifications. Confirm the package type is the 64-pin HTQFP PowerPAD variant. Ensure the operating temperature range meets industrial requirements of -40°C to 85°C. Check datasheet revision SLLS591C for accurate electrical characteristics.

Selection Notes

Select this component when replacing parallel buses with serial links to save board space. Ensure the system requires a 2.5-V supply voltage. Verify that the interface supports 18-bit parallel data width. Consider the thermal performance of the PowerPAD package for heat dissipation needs.

Part Context

The TLK1521 belongs to the WizardLink family of multi-gigabit transceivers designed by Texas Instruments. It is engineered for physical layer interface devices requiring parallel-to-serial and serial-to-parallel conversion functions within high-speed communication systems.
