CRD4202-2 Datasheet | Cirrus Logic

Features Phase Locked Loop (PLL) Codec Operation Six Channel Analog Audio Outputs Headphone Sense using GPIO CS4202 codec and two CS4334 DACs 20-bit D to A conversion (DAC) 18-bit A to D conversion (ADC) S/PDIF (IEC-958) optical digital output plete suite of Analog I/O connections: - Line, Mic, CD, Video, Modem, and Aux Inputs - Modem, Headphone, Line Front, Line Rear and Line Center/Sub-Woofer Outputs Description The CRD4202-2 reference design eliminates the cost of the 24.567 MHz crystal by operating the CS4202 in Phase Locked Loop (PLL) mode. This reference design also features six channel analog audio outputs, an optical S/PDIF digital output, and munication and Networking Riser (CNR) interface. This design uses the CS4202 audio codec which has several advanced features including a built-in headphone amplifier, simultaneous six channel analog and S/PDIF optical digital output, GPIO for headphone detection, and up to 30 d B of internal microphone boost. The CRD4202-2 reference design is available by ordering the CMK4202-2 manufacturing kit. This kit includes the CRD4202-2 board, a full set of schematic design files (Or CAD® format), PCB job files (PADS® ASCII), PCB artwork files, and bill of materials. This reference design offers significant cost savings over peting solutions and can be easily modified to meet your specific design goals.
