NXP Semiconductors TDA9983BHW/15/C1,5

Overview

TDA9983BHW/15/C1,5 from NXP Semiconductors is a 150 MHz pixel rate HDMI 1.2a transmitter supporting RGB/YCBCR 4:4:4 and YCBCR 4:2:2 video inputs, up to four I2S-bus audio streams (192 kHz sampling), and S/PDIF audio - deployed in set-top boxes, AV receivers, and media players for high-fidelity digital video/audio interface conversion.

For engineers reviewing the TDA9983BHW/15/C1,5 datasheet, TDA9983BHW/15/C1,5 pinout, TDA9983BHW/15/C1,5 application, or TDA9983BHW/15/C1,5 equivalent, key selection criteria include HDMI serializer clock capability (150 MHz max pixel rate), dual-supply operation (1.8 V core / 3.3 V I/O), programmable input formatter for ITU656-like and semi-planar formats, and integrated intrafield deinterlacer with upscaling to 720p/1080i.

Technical Context

The TDA9983BHW/15/C1,5 implements three dedicated PLLs: a double-edge VCLK PLL for video input capture, a scaling PLL generating processed video clocks per scaler ratio, and a serializer PLL producing HDMI TMDS clock ≥10× audio sample rate. Its video input processor accepts three 8-bit ports (VPA/VB/VC) with configurable edge-sampling (rising/falling/both) and supports embedded (SAV/EAV) or external sync modes.

Audio handling includes four independent I2S-bus stereo inputs (AP1–AP4) plus AP6 for S/PDIF, with automatic clock recovery from S/PDIF or optional MCLK on AP5. The color space converter (RGB ↔ YCBCR) and upsampler/downsampler blocks are fully programmable via I²C, enabling format adaptation without external logic.

FAQ

What video input formats does the TDA9983BHW/15/C1,5 support?

The TDA9983BHW/15/C1,5 supports RGB 4:4:4 (3×8-bit), YCBCR 4:4:4 (3×8-bit), YCBCR 4:2:2 semi-planar (up to 2×12-bit), and YCBCR 4:2:2 ITU656-like (up to 1×12-bit). It accepts both external synchronization (HSYNC/VSYNC/DE) and embedded sync (SAV/EAV), with configurable edge sampling on VCLK. These capabilities are confirmed in Tables 5–13 of the official NXP datasheet for TDA9983BHW/15/C1,5.

Does the TDA9983BHW/15/C1,5 support HDMI 2.0 or higher?

No, the TDA9983BHW/15/C1,5 is compliant with HDMI 1.2a only, supporting up to 150 MHz pixel rate (1080p60 RGB) and features defined in that specification - including deep color and xvYCC are not supported. It does not implement HDMI 2.0 features such as 4K resolution, HDR metadata, or increased bandwidth. This limitation is explicitly stated in the General Description and Functional Description sections of the NXP TDA9983BHW/15/C1,5 datasheet.

How is audio handled on the TDA9983BHW/15/C1,5?

The TDA9983BHW/15/C1,5 supports two mutually exclusive audio modes: either four I2S-bus stereo inputs (AP1–AP4, up to 8 channels total) or one S/PDIF input (AP6) carrying uncompressed PCM or compressed Dolby Digital/DTS bitstreams. Audio format selection is controlled via I²C registers. The device recovers clock from S/PDIF internally or accepts an external MCLK on AP5 - all details are specified in Sections 8.8–8.10 of the TDA9983BHW/15/C1,5 datasheet.

What power supply requirements does the TDA9983BHW/15/C1,5 have?

The TDA9983BHW/15/C1,5 requires five distinct supplies: VDDC(1V8) = 1.65–1.95 V (digital core), VDDA(FRO_3V3) and VDDA(PLL_3V3) = 3.0–3.6 V (analog oscillator/PLL), VDDD(3V3) = 3.0–3.6 V (input ports), and VDDH(3V3) = 3.0–3.6 V (HDMI transmitter). Power-up sequencing is mandatory - VDDD and VDDC must follow the order shown in Figure 14 of the datasheet to prevent latch-up or initialization failure.

Is the TDA9983BHW/15/C1,5 pin-compatible with other TDA9983 variants?

Yes, the TDA9983BHW/15/C1,5 shares the identical HTQFP80 (SOT841-4) package and pinout with all TDA9983BHW variants including /8 and /15 versions. Differences are limited to internal speed grade (81 MHz vs. 150 MHz pixel rate) and factory programming; no PCB layout change is required when upgrading from TDA9983BHW/8/C1 to TDA9983BHW/15/C1,5 - confirmed in Table 2 (Ordering Information) and Pin Description sections of the datasheet.
