TLK3114SCGPV

Drivers, Receivers, Transceivers Overview

The TLK3114SC is a quad serial transceiver delivering up to 10 Gbps of bidirectional point-to-point data transmission. It supports serial data rates from 2.5 Gbps to 3.125 Gbps and operates with a single 2.5-V power supply while dissipating less than 3 W. The device provides parallel-to-serial and serial-to-parallel conversion, clock extraction, and selectable 8-b/10-b encoding. It features VML differential signaling for the transmitter and on-chip receive equalization. Packaged in a 19-mm × 19-mm, 289-terminal plastic ball grid array (PBGA), it is characterized for operation from 0°C to 70°C.

• Features selectable synchronized or independent channel operation with on-chip 8-b/10-b encode/decode functionality.
• Includes MDIO management interface and IEEE 1149.1 JTAG test port for configuration and manufacturing testing.
• Supports hot-plug protection and built-in pseudorandom bit stream (PRBS) generation and verification.

Drivers, Receivers, Transceivers Applications

• Chip-to-chip implementation providing extended trace distance between switching fabric and optical transceiver modules.
• Physical coding sublayer (PCS) implementation connecting to coarse wavelength division multiplexed optical transceivers.
• System backplane interconnect linking MAC/packet processors to framer/PCS PHY/optics line cards.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the latest Package Option Addendum on the Texas Instruments website to ensure correct package type and temperature range. Confirm that the design utilizes the compatible terminal layout for the 289-terminal MicroStar BGA package. Ensure the system design accounts for the single 2.5-V supply requirement and thermal dissipation limits under maximum operating conditions.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed bidirectional data transmission up to 3.125 Gbps per channel. It serves as a direct replacement for the TLK3104SA in existing board designs due to terminal compatibility. Consider its support for both XGMII and XAUI standards if extending PCB trace distances or interfacing with CWDM optics is required.

Drivers, Receivers, Transceivers Part Context

The TLK3114SC belongs to a family of CMOS multi-gigabit transceivers designed for high-speed point-to-point data transmission. It is manufactured using mainstream 250-nm CMOS technology. The device is part of Texas Instruments' Serial Gigabit Products portfolio, intended for applications demanding reliable data transfer over controlled-impedance media such as PCB traces, copper cables, or fiber-optic links.

Drivers, Receivers, Transceivers Replacement Considerations

The TLK3114SC is terminal compatible with the TLK3104SA quad serial transceiver. Designs utilizing the TLK3104SA can be upgraded to the TLK3114SC without modifying the board layout, provided the software configuration supports the updated device capabilities.
