TDA8754HL/14/C1,55

ADCs/DACs - Special Purpose Overview

The TDA8754HL/14/C1,55 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 Msample/s. The device includes analog preprocessing functions such as clamping and programmable gain amplifiers (PGA), optimized for capturing RGB/YUV graphic signals. It supports display resolutions up to QXGA (2048 × 1536) at 85 Hz. The component operates with analog and digital supply voltages ranging from 3.0 V to 3.6 V, with a typical value of 3.3 V. It is housed in a 144-lead LQFP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix /C1,55 against official documentation, as standard listings often cite /14 or /11 variants. Confirm RoHS compliance status and lead-free soldering parameters prior to integration. Check current product availability as older video ADC models may have limited stock or end-of-life status.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high-speed conversion of RGB or YUV signals with integrated clock recovery. Ensure the design accommodates the 144-pin LQFP footprint and provides adequate decoupling for the multiple analog and digital power domains. Verify that the host system can manage the I²C configuration registers for clamp levels and gain settings.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TDA8754 family of triple high-speed video ADCs. The 'HL' designation indicates the LQFP144 plastic low profile quad flat package variant. Other package options include the LBGA208 (EL series). Different suffixes like /11, /14, /17, /21, and /27 typically denote different guaranteed maximum sampling frequencies within the device's capability.
