Product details
Overview
TDA9981BHL/15/C1:5 from NXP Semiconductors is an HDMI 1.2a-compliant transmitter IC supporting up to 150 MHz pixel rate, 3 × 8-bit RGB/YCbCr video input, four I2S-bus audio streams (up to 192 kHz), and S/PDIF audio - deployed in set-top boxes, AV receivers, and media players for HDMI/DVI interface bridging.
For engineers reviewing the TDA9981BHL/15/C1:5 datasheet, TDA9981BHL/15/C1:5 pinout, TDA9981BHL/15/C1:5 application, or TDA9981BHL/15/C1:5 equivalent, key selection considerations include HDMI serializer clock range (250 MHz–1.5 GHz), dual-edge sampling capability on VCLK, programmable color space conversion (RGB ↔ YCbCr), and multi-format video input support (ITU656-like, semi-planar 4:2:2, embedded sync).
Technical Context
The TDA9981BHL/15/C1:5 integrates two PLLs: a double-edge PLL for video input capture at up to 150 MHz and a serializer PLL generating HDMI link clocks ≥10× audio sample rate. It supports real-time format remapping across three independent 8-bit video ports (VPA/VBP/VPC) with configurable bus inversion and port swapping.
Its video input processor accepts RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2 semi-planar (2×12-bit), and ITU656-like (1×12-bit) formats - with double-edge sampling enabled for ITU656-like inputs. The color space converter is fully programmable via I²C and can be bypassed; upsampling from 4:2:2 to 4:4:4 uses linear interpolation or pixel repetition.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TFP401APZPR | Single-link DVI transmitter only; no HDMI audio embedding, no S/PDIF, no I2S, no programmable formatter | Limited to video-only DVI applications; requires external audio mux and clocking | Select when HDMI audio transport is unnecessary and cost sensitivity outweighs feature flexibility |
| Maxim MAX9516ETL+ | Integrated video DAC + HDMI transmitter; supports only 8-bit RGB/YUV; max 108 MHz pixel clock; no ITU656 support | Suitable for lower-resolution displays (720p); lacks 1080p60 capability and multi-format adaptability | Choose for compact, low-power 720p designs where video-only output suffices and footprint is critical |
Compared with TFP401APZPR and MAX9516ETL+, the TDA9981BHL/15/C1:5 uniquely delivers HDMI 1.2a compliance with embedded audio, ITU656-like input handling, and 150 MHz pixel clock - making it the only option among the three capable of full 1080p60 HDMI transmission with native S/PDIF/I2S audio integration.

FAQ
What video input formats does the TDA9981BHL/15/C1:5 support?
The TDA9981BHL/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 handles both external synchronization (HSYNC/VSYNC/DE) and embedded sync (SAV/EAV), with double-edge sampling enabled for ITU656-like formats. All formats are configurable via I²C registers.
Does the TDA9981BHL/15/C1:5 support HDMI audio embedding?
Yes, the TDA9981BHL/15/C1:5 supports full HDMI 1.2a audio embedding. It accepts up to four I2S-bus stereo streams (8 channels total) or one S/PDIF stream (2-channel PCM or compressed multichannel audio like Dolby Digital). Audio format selection is controlled via I²C; only one audio source (I2S or S/PDIF) may be active at a time.
What is the maximum pixel clock frequency supported by the TDA9981BHL/15/C1:5?
The TDA9981BHL/15/C1:5 supports a maximum pixel clock frequency of 150 MHz, as confirmed by its /15 variant designation and Quick Reference Data table. This enables native 1080p60 RGB/YCbCr 4:4:4 transmission and supports higher-resolution modes such as WUXGA (1920×1200@60Hz) with timing margin.
How is the HDMI output swing adjusted on the TDA9981BHL/15/C1:5?
The HDMI output swing on the TDA9981BHL/15/C1:5 is set using the EXT_SWING pin (Pin 24), which connects to VDDH(3V3) via a fixed resistor. The resistor value determines the output amplitude per HDMI specification - typical values range from 27 Ω to 56 Ω depending on PCB trace impedance and cable length. No register programming is required for this analog adjustment.
Is the TDA9981BHL/15/C1:5 pin-compatible with other TDA9981 variants?
Yes, all TDA9981B variants including TDA9981BHL/8/C1:5 and TDA9981BHL/15/C1:5 share identical LQFP80 (SOT315-1) packaging and pinout. The /8 and /15 suffixes denote maximum pixel clock capability (81 MHz vs. 150 MHz) and corresponding internal PLL tuning - electrical and mechanical compatibility is maintained across the family.
