CK49x System Description CK49x User’s Manual The CS4953xx/CS4970x4 has many applications stored in internal ROM, but a host is still required to configure the application for a particular system. The CK49x allows the PC to act as a host to boot and configure the DSP through the GUI software. The DSP is booted primarily from external serial Flash (U13 on CDB49x) using the DSP Condenser system for simplified MCU control. 1.3.
CK49x System Description CK49x User’s Manual 1.3.17 HDMI Recevier (RX) The Silicon Image™ Si9135 HDMI Rx (U16) is used for the HDMI input on the CK49x. It can provide up to 4 lines of I2S data which can support PCM, legacy compressed audio (DD, DTS), and new HD audio streams. Because the Si9135 responds to all I2C addresses, a bus isolator (U14) has been used to prevent the HDMI Rx from responding to serial communication intended for other devices on the CK49x. 1.3.
