Overview of Texas Instruments TDP158

O TDP158 is a sophisticated redriver that translates AC-coupled HDMI signals into TMDS (Transition-Minimized Differential Signaling), ensuring optimal signal quality and minimizing data loss over extended cable runs or challenging board traces. Supporting HDMI 1.4b and 2.0b standards, the TDP158 is engineered to handle four TMDS channels and the Digital Display Control (DDC) interface.

Principais características

• High Compatibility: The device supports DVI 1.0 and HDMI 2.0b standards, making it versatile for various multimedia applications.
• High Data Rates: It can operate at signaling rates up to 6Gbps, ensuring compatibility with 4k2k resolution displays at 60Hz (24 bits per pixel) or WUXGA with 16-bit color depth.
• Eficiência energética: Dual power supply rails (1.1V on VDD and 3.3V on VCC) and several power management techniques allow the TDP158 to function efficiently with reduced power consumption.
• Advanced Signal Conditioning: The device supports up to 15.5dB fixed receiver EQ gain, programmable through I2C or pin strap to compensate for varying input cable lengths and traces.

Signal Integrity and Performance Enhancements

Signal integrity is paramount for digital video interfaces, especially when working with high-resolution outputs like 4k2k. The TDP158’s built-in equalization and signal conditioning features ensure that even long or sub-optimal cables do not result in significant data loss.

Detailed Performance Capabilities

• Programmable Equalization: This feature allows users to adjust for cable length variations, optimizing the signal for each application.
• Global and Independent Lane Control: The TDP158 offers fine-grained control over pre-emphasis, transmit swing, and slew rate on each TMDS channel, ensuring high signal integrity and reduced noise.
• Low Power Operation: The TDP158 consumes only 200mW of power during active operation at 6Gbps, and it drops to a mere 8mW in shutdown mode, making it highly efficient.

Power Management and Efficiency

Power consumption is a critical consideration, particularly for portable devices like notebooks and tablets. Texas Instruments has equipped the TDP158 with dual power supply rails that operate at 1.1V and 3.3V, reducing the overall power demand without compromising performance. Multiple power management techniques have been implemented to minimize active power usage and significantly lower consumption in idle states.
