| Low Power HDMI/DVI Transmitter with Consumer Electronic Control (CEC) ADV7520NK FEATURES General Low power HDMI/DVI transmitter ideal for portable applications CEC controller and buffer reduce system overhead Compatible with HDMI v.1.3, DVI v.1.0, and HDCP 1.3 Supports xvYCC functionality Single 1.8 V power supply Video/audio inputs accept logic levels from 1.8 V to 3.3 V Digital video 80 MHz operation supports all HDTV resolutions from 480i to 1080i Programmable 2-way color space converter Supports RGB, YCbCr, and DDR Supports ITU656-based embedded syncs Automatic input video format timing detection (CEA-861D) Digital audio Supports standard S/PDIF for stereo LPCM or compressed audio up to 192 kHz 8-channel, uncompressed LPCM I2S audio up to 192 kHz Special features for easy system design On-chip MPU with I2C master to perform HDCP operations and EDID reading operations 5 V tolerant I2C and HPD I/Os, no extra device needed No audio master clock needed for supporting S/PDIF and I2S On-chip MPU reports HDMI events through interrupts and registers FUNCTIONAL BLOCK DIAGRAM SCL SDA MCL MDA INT I2C SLAVE HDCP CORE HDCP AND EDID MICROCONTROLLER HPD REGISTERCON FIGURATION LOGIC CLK VSYNC HSYNC DE D[23:0] VIDEO DATA CAPTURE I2C MASTER CEC CONTROLLER BUFFER SYNC ADJUSTMENT AND GENERATION DDCSCL DDCSDA CEC Tx0[1:0] S/PDIF MCLK I2S[3:0] LRCLK SCLK AUDIO DATA CAPTURE COLOR SPACE CONVERSION Tx1[1:0] HDMI Tx CORE Tx2[1:0] TxC[1:0] ADV7520NK Figure 1. The ADV7520NK supports both S/PDIF and 8-channel I2S audio. Its high fidelity, 8-channel I2S can transmit either stereo or 7.1 surround audio at 192 kHz. The S/PDIF can carry stereo linear pulse-code modulation (LPCM) audio or compressed audio, including Dolby(R) Digital and DTS(R). The ADV7520NK helps reduce system design complexity and cost by incorporating such features as an internal microprocessor for high-bandwidth digital content protection (HDCP) operations, an I2C(R) master for extended display identification data (EDID) reading, a single 1.8 V power supply, and 5 V tolerance on the I2C and hot plug detect pins. For additional information and resources, see the Applications Information section. Fabricated in an advanced CMOS process, the ADV7520NK is available in a space saving, 76-ball CSP_BGA. The package is RoHS compliant and is specified for -25C to +90C operation. APPLICATIONS Digital video cameras Digital still cameras Personal media players Cellular handsets DVD players and recorders Digital set-top boxes A/V receivers HDMI repeater/splitter GENERAL DESCRIPTION The ADV7520NK is an 80 MHz, high definition multimedia interface (HDMITM) v.1.3 transmitter with consumer electronic control (CEC). It supports HDTV formats up to 720p and 1080i and computer graphic resolutions up to XGA (1024 x 768 @ 75 Hz). With the inclusion of HDCP, the ADV7520NK allows the secure transmission of protected content, as specified by the HDCP 1.3 protocol.
