Digital audio GENERAL DESCRIPTION Supports standard SPDIF for stereo LPCM or compressed audio up to 192 kHz The ADV7526 is a 150 MHz, high definition multimedia 2 8-channel uncompressed LPCM I S audio up to 192 kHz interface (HDMI) transmitter with expanded CEC buffer. It Special features for easy system design supports HDTV formats up to 1080p and computer graphic 2 On-chip MPU with I C master to perform EDID reading and resolutions up to SXGA at 75 Hz. HDCP operations reports HDMI events through interrupts With the inclusion of embedded HDCP keys, the ADV7526 and registers allows the secure transmission of protected content, as specified 2 5 V tolerant I C and HPD I/Os, no extra device needed by the HDCP 1.3 protocol. No audio master clock needed for supporting SPDIF 2 2 The ADV7526 supports both SPDIF and 8-channel I S audio. and I S 2 Its high fidelity 8-channel I S can transmit stereo up to a 192 kHz Compatible with AD9394 HDMI companion chip sampling rate. The SPDIF can carry stereo LPCM audio or 5 V generator for Hot Plug detect in portable applications compressed audio, including Dolby Digital and DTS. APPLICATIONS The ADV7526 helps to reduce system design complexity and Cellular handsets 2 cost by incorporating such features as an I C master for EDID Digital video cameras 2 reading and 5 V tolerance on the I C and Hot Plug detect pins. Digital still cameras Fabricated in an advanced CMOS process, the ADV7526 is Personal media players available in a space-saving, 64-ball, WLCSP surface-mount Gaming package. This package is RoHS compliant and specified to DVD players and recorders operate from 25C to +85C.
