Analog Devices, Inc. (ADI) today introduced the ADV7521NK, the industry’s smallest, low-power HDMI™ v 1.3 (High-Definition Multimedia Interface™) transmitter that enables video delivery to HD televisions from portable multimedia devices, including digital still and DSLR cameras, camcorders, portable media players and cell phones. A new addition to ADI’s Advantiv® advanced television solutions portfolio, the ADV7521NK is the world’s smallest (only 3.5 mm × 3.5 mm × 0.65 mm) HDMI v 1.3 transmitter with on-chip support for Consumer Electronic Control (CEC), which enables a single remote control to run multiple CEC-enabled high-definition (HD) devices, eliminating the need for separate remotes for each HD device. The ADV7521NK’s small form factor, low power dissipation and CEC interface enable designers to speed to market smaller, lighter and more affordable HD-enabled devices that work seamlessly within home entertainment systems — with only one cable connection and a single remote control.

With low power and on-chip CEC support, the ADV7521NK also addresses market demand for high-performance transmit ICs that reduce system cost and HDMI design complexity, enabling engineers to design products with high-end HD functionality across multiple performance and price points.

"As the world's smallest and thinnest single-chip HDMI v1.3 transmitter, the ADV7521NK enables high-performance HDMI connectivity in portable consumer electronics where size and weight are of critical importance," said Bill Bucklen, director, Advanced Television Segment, Analog Devices. "With low power and on-chip CEC support, the ADV7521NK also addresses market demand for high-performance transmit ICs that reduce system cost and HDMI design complexity, enabling engineers to design products with high-end HD functionality across multiple performance and price points."

The low-power transmitter offers full support for HDTV (high-definition television) video standards up to 1080p/30f, 1080i/60f, 720p/60f and computer graphics standards up to XGA at 75Hz. In addition, the ADV7521NK incorporates the industry's leading connectivity standards including HDMI v1.3 (supporting x.v.Color™), the Consumer Electronics Association's CEA-861-D, and DVI v1.0 (digital video interface).

The ADV7521NK leverages the advanced core of the previously announced ADV7520/ADV7520NK. This core provides extremely low standby power, enabling designers to significantly extend battery life in portable multimedia devices where standby mode can account for as much as 90 percent of the duty cycle.

ADI's new HDMI v 1.3 transmitter helps reduce system cost by incorporating features such as I2C (inter-integrated circuit) master for EDID (extended display identification data) reading, a single 1.8-V power supply and 5-V tolerant I/Os that support I2C and HPD (Hot Plug Detect). Unlike competitive offerings, ADV7521NK eliminates the need for external voltage translators and converts I/O signals from 5 V or 3.3 V to 1.8 V, further reducing design complexity and extending battery life in portable electronics.

The ADV7521NK provides complete audio support for S/PDIF (Sony/Philips digital interface format) for LPCM (linear pulse code modulation) audio or compressed audio including Dolby Digital® and DTS®; and 2-channel I2S audio for transmitting stereo at sample rates up to 192 kHz.

The ADV7521NK is compatible with other Analog Devices components in the advanced TV signal chain, including the ADV7390–93 video encoders; ADV7441A 10-bit integrated, multi-format SDTV (standard-definition television)/HDTV video decoder, RGB graphics digitizer, and 2:1 multiplexed HDMI/DVI interface; and AD8190/1/2/5/6/7A/7B HDMI/DVI switches and buffers with equalization.

Pricing and Availability

The ADV7521NK HDMI v 1.3 transmitter is available now in full production quantities. The ADV7521NK is fabricated in an advanced CMOS process and is available in a space-saving, 49-ball, WLCSP (Wafer Level Chip Scale Package). It is specified over the –25 degrees C to +85 degrees C temperature range. The ADV7521NK is priced at $3.11 per unit in 1,000-piece quantities. For more information, please visit
