Product details
Overview
ADV7541BCBZ-2RL from Analog Devices is a low-power HDMI/DVI transmitter IC with integrated de-interlacer and CEC controller, supporting 150 MHz video up to 1080p, x.v.Color™ wide-gamut color, and HDCP 1.3 with embedded keys. It accepts 1.8 V–3.3 V logic inputs, operates on single 1.8 V supply, and targets portable media devices requiring compact, power-efficient HDMI output.
For engineers reviewing the ADV7541BCBZ-2RL datasheet, ADV7541BCBZ-2RL pinout, ADV7541BCBZ-2RL application, or ADV7541BCBZ-2RL equivalent, key selection criteria include TMDS output compliance (HDMI v1.4/DVI v1.0), de-interlacer memoryless operation (480i–1080i), 5 V-tolerant DDC/I2C/HPD I/Os, and WLCSP package constraints for high-density PCB layout.
Technical Context
The ADV7541BCBZ-2RL implements a full HDMI 1.4 transmitter stack including TMDS encoder, HDCP 1.3 core with embedded keys, and on-chip microcontroller for EDID management and interrupt reporting. Its de-interlacer uses internal line buffers-no external memory-and supports auto-detection of CEA-861E timing formats.
It integrates dual audio interfaces (S/PDIF and 2-channel I2S) with 192 kHz support, programmable color space conversion (RGB/YCbCr), and CEC controller with external clock input (1–100 MHz). All digital I/Os are 5 V tolerant except video/audio data lines, simplifying level-shifting in mixed-voltage systems.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Memoryless De-Interlacer | Converts 480i–1080i interlaced sources to progressive 1080p output using only on-chip line buffers-no external memory BOM or layout area required |
| x.v.Color™ Support | Enables wider color gamut transmission per HDMI v1.4 specification, improving visual fidelity for BT.709/BT.2020 content without software modification |
| Integrated I2C Master | Automatically reads EDID from connected display and manages HDCP authentication handshake-reduces host MCU firmware overhead and boot time |
| 5 V-Tolerant DDC/HPD/I2C | Eliminates need for discrete level-shifting components on DDC and HPD lines, lowering BOM cost and board area in 1.8 V/3.3 V systems |
| Single 1.8 V Supply | Reduces power delivery complexity by consolidating AVDD and DVDD rails; total power is 125 mW (de-interlacer off) or 295 mW (1080i→1080p) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7543BCBZ-2RL | Same WLCSP package and pinout; adds built-in 3D video format support and enhanced HDCP 2.2 readiness via firmware update path | Required for 3D Blu-ray playback or future-proofing against HDCP 2.2 mandates; higher BOM cost and larger firmware footprint | Select ADV7543BCBZ-2RL only if 3D video transport or HDCP 2.2 upgrade path is mandatory; otherwise ADV7541BCBZ-2RL offers optimal cost/performance for 2D HDMI 1.4 |
| Si2920-A2-AK | QFN-64 package; supports HDMI 1.3a only; no integrated de-interlacer or CEC; requires external HDCP keys and EDID EEPROM | Suitable for fixed-format, non-portable designs where board space is less constrained and system MCU handles CEC/EDID | Choose Si2920-A2-AK for legacy HDMI 1.3a systems with existing QFN layout and no de-interlacing requirement; not drop-in compatible due to package and pin count mismatch |
Compared with ADV7543BCBZ-2RL and Si2920-A2-AK, the ADV7541BCBZ-2RL uniquely balances low-power operation, memoryless de-interlacing, and embedded HDCP 1.3 in a 49-ball WLCSP-making it the optimal choice for battery-powered portable devices requiring HDMI 1.4 compliance without 3D or HDCP 2.2 overhead.

FAQ
Does ADV7541BCBZ-2RL support HDMI 1.4 features like x.v.Color™ and 3D video?
Yes, ADV7541BCBZ-2RL supports x.v.Color™ (Gamut Metadata) for extended color gamut per HDMI 1.4, but does not support native 3D video formats. Its HDMI compliance is defined as v1.4 for timing, audio, and metadata features-3D transport requires ADV7543BCBZ-2RL or later variants. The ADV7541BCBZ-2RL datasheet explicitly confirms x.v.Color™ implementation and lists CEA-861E infoframe support.
What is the function of the REXT pin on ADV7541BCBZ-2RL?
The REXT pin on ADV7541BCBZ-2RL sets internal reference currents for TMDS output drivers and PLL circuits. A 3.92 kΩ ±1% resistor must be connected between REXT and GND to calibrate output swing and jitter performance. Omitting or misvaluing this resistor causes TMDS signal integrity failure and HDMI link instability. This requirement is specified in the Pin Configuration section of the ADV7541BCBZ-2RL datasheet.
Can ADV7541BCBZ-2RL operate without an external crystal for CEC functionality?
No-ADV7541BCBZ-2RL requires an external clock source (1 MHz to 100 MHz) on the CECCLK pin to drive the CEC controller; no internal oscillator is provided. The default configuration uses a 12 MHz crystal, as noted in the Electrical Specifications table. Without this clock, CEC communication fails entirely, though HDMI video/audio remains functional. This dependency is documented in the Pin Function Descriptions and CEC timing specifications for ADV7541BCBZ-2RL.
Is ADV7541BCBZ-2RL pin-compatible with ADV7541BCBZ-P-2RL?
Yes-ADV7541BCBZ-2RL and ADV7541BCBZ-P-2RL share identical pinout, package (CB-49-2 WLCSP), and electrical characteristics; the only difference is embedded HDCP 1.3 keys (present in ADV7541BCBZ-2RL, absent in ADV7541BCBZ-P-2RL). Both parts are mechanically and electrically interchangeable on PCBs, allowing secure vs. non-secure variants to be swapped without layout changes.
What audio formats does ADV7541BCBZ-2RL support natively?
ADV7541BCBZ-2RL supports two native audio interfaces: 2-channel I2S (up to 192 kHz sampling rate) and S/PDIF (carrying stereo LPCM or compressed Dolby Digital/DTS bitstreams). It does not require an external MCLK for S/PDIF operation-the SCLK pin serves as MCLK when configured for S/PDIF. These capabilities are confirmed in the General Description and Audio AC Timing sections of the ADV7541BCBZ-2RL datasheet.
