TDA8754HL/14/C1,51

ADCs/DACs - Special Purpose Overview

The TDA8754HL/14/C1,51 is a triple 8-bit video analog-to-digital converter (ADC) manufactured by NXP USA Inc. It features an integrated phase-locked loop (PLL) capable of generating sampling clocks up to 270 MHz. The device supports dual-port data output modes, achieving maximum data rates of 140 MHz in single-port mode and 270 MHz in dual-port mode. It includes analog preprocessing functions such as programmable gain amplifiers (PGA) and clamp circuits optimized for RGB/YUV signals. The component operates on a 3.3 V supply with a commercial temperature range of -10°C to +70°C and is housed in a 144-LQFP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix /14/C1,51 against current manufacturer documentation to confirm the 140 MHz sampling frequency rating and RoHS compliance status. Confirm package type LQFP144 matches design requirements. Check for obsolescence notices or end-of-life declarations prior to final procurement decisions.

ADCs/DACs - Special Purpose Selection Notes

Select this model when a triple-channel 8-bit conversion is required for RGB or YUV signals with sampling rates up to 140 MHz. Ensure the system design accommodates the 144-pin LQFP footprint and provides separate 3.3 V supplies for analog (VCCA), digital (VCCD), and output (VCCO) sections. Verify I2C bus compatibility for configuration control.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TDA8754 family of video ADCs. The 'HL' designation indicates the LQFP144 plastic low profile quad flat package variant. The '/14' suffix specifies the 140 MHz sampling frequency grade within the series, which also includes variants rated for 110, 170, 210, and 270 MHz.

ADCs/DACs - Special Purpose Replacement Considerations

Other sampling grades within the same package, such as TDA8754HL/11, TDA8754HL/17, TDA8754HL/21, or TDA8754HL/27, offer pin-compatible alternatives with different maximum sampling frequencies.
