TDA8754HL/17/C1,51

ADCs/DACs - Special Purpose Overview

The TDA8754HL/17/C1,51 is a triple 8-bit video analog-to-digital converter manufactured by NXP USA Inc. It features an integrated phase-locked loop (PLL) capable of generating sampling clocks up to 270 MHz and supports display resolutions up to QXGA at 85 Hz. The device includes analog preprocessing functions such as clamping and programmable gain amplifiers optimized for RGB/YUV signals. It operates on a 3.3 V supply with a commercial temperature range of -10°C to +70°C. Key electrical parameters include a maximum data rate of 140 MHz in single-port mode and 270 MHz in dual-port mode, utilizing LV-TTL outputs.

ADCs/DACs - Special Purpose Feature Summary

• Triple 8-bit ADCs with 0.25 LSB DNL and 0.6 LSB INL performance
• Integrated PLL supporting sampling rates from 12 Msps to 270 Msps
• Analog preprocessing including three independent clamp circuits and AGC
• I2C-bus interface for control of gains, clamp levels, and PLL settings

ADCs/DACs - Special Purpose Applications

• LCD panel drive systems
• RGB/YUV high-speed digitizing
• LCD projection systems
• New TV concept designs

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix /C1,51 against official documentation, as standard variants are typically designated by HL/17 without this suffix. Confirm package type LQFP144 and check current availability status, as older TDA8754 variants may be discontinued or subject to last-time buy notices.

ADCs/DACs - Special Purpose Selection Notes

Select the TDA8754HL/17 variant when a guaranteed sampling frequency of 170 MHz is required. Ensure the design accommodates the 144-pin LQFP package dimensions. Verify that the application requires the specific analog bandwidth and sync processing capabilities provided by this IC compared to other members of the TDA875x family.

ADCs/DACs - Special Purpose Part Context

This component belongs to the TDA875 series of video ADCs. The 'HL' designation indicates the LQFP144 plastic low profile quad flat package. The '/17' suffix specifies the guaranteed sampling frequency class of 170 MHz. Other variants in the series offer different speed grades ranging from 110 MHz to 270 MHz.

ADCs/DACs - Special Purpose Replacement Considerations

The TDA8754EL/17 offers the same functional specifications but utilizes an LBGA208 package. Pin-to-pin compatibility exists between the LQFP144 and LBGA208 packages only if the board layout supports both form factors; otherwise, redesign is required.
