TLK1521IPAPG4

Overview

The TLK1521IPAPG4 is a WizardLink serializer/deserializer supporting serial data rates from 500 Mbps to 1.3 Gbps with an effective payload of 450 Mbps to 1.17 Gbps. It utilizes an 18-bit parallel interface and operates on a 2.5-V supply, consuming approximately 288 mW at maximum speed. The device features selectable signal preemphasis, internal loopback for testing, and hot-plug protection. It is housed in a 64-pin HTQFP PowerPAD package rated for industrial temperatures between -40°C and 85°C.

Feature Summary

• Supports high-speed bidirectional point-to-point data transmission over copper cables or backplanes
• Includes selectable signal preemphasis to compensate for inter-symbol interference in lossy media
• Provides rapid synchronization mode using specific SYNC patterns for deterministic link initialization
• Features internal loopback capability for functional self-testing of the physical interface

Applications

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

Procurement Notes

Verify the complete part number including the PG4 suffix to ensure compliance with current manufacturing standards. Confirm that the 64-pin HTQFP PowerPAD package requirements are met during PCB layout, specifically regarding the thermal pad soldering for proper electrical grounding and heat dissipation.

Selection Notes

Select this component when designing interfaces requiring speeds up to 1.3 Gbps with an 18-bit parallel bus. Ensure the system provides a reference clock within ±100 PPM tolerance. Consider the 2.5-V power supply requirement and verify that the transmission medium supports the necessary impedance characteristics for the differential outputs.

Part Context

This device belongs to Texas Instruments' WizardLink family of multi-gigabit transceivers. It is designed to replace traditional parallel data transmission architectures by consolidating multiple traces into a single serial channel. The IPAPG4 designation indicates the specific package type and lead-free processing compliant with RoHS directives.
