Product details
Overview
TDA19988AHN/C189551 from NXP Semiconductors is a low-power HDMI 1.4a transmitter with integrated HDCP 1.4 cipher, CEC controller, and programmable video formatter. It supports 3×8-bit RGB/YCbCr input at up to 165 MHz pixel rate, S/PDIF or I²S audio up to 192 kHz, and operates in HVQFN64 package (9 mm × 9 mm). It targets mobile and STB applications requiring compact size, battery efficiency, and secure HDMI output.
For engineers reviewing the TDA19988AHN/C189551 datasheet, TDA19988AHN/C189551 pinout, TDA19988AHN/C189551 application, or TDA19988AHN/C189551 equivalent, key selection criteria include TMDS output swing control, I²C-configurable video format mapping (RGB/YCbCr/ITU656), embedded DDC master for EDID read, HDCP key storage in OTP, and CEC open-drain interface compliance with HDMI 1.4a.
Technical Context
The TDA19988AHN/C189551 integrates a PLL-based serializer generating 10× pixel-rate TMDS clocks, a three-port video input formatter supporting external or embedded sync, and a color space converter (RGB↔YCbCr) with configurable bit-swapping per port. Its video processing pipeline accepts RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2 semi-planar (up to 2×12-bit), and ITU656-like formats with selectable single/dual-edge sampling.
Audio handling includes four I²S lanes or one S/PDIF lane, synchronized via ACLK; HDCP 1.4 authentication uses internal SHA-1 and OTP-stored keys; CEC operates as a bidirectional open-drain bus; and power management enables Standby mode (18 µW typical) and dynamic operation scaling from 720p24 (55 mW) to full bandwidth.
