stac9227/9228/9229/9230 are high fidelity, 8-channel audio code cs compatible with the intel high definition (hd) audio interface. the stac 9227/9228/9229/9230 codecs provide high quality, hd audio capability to noteb ook and cost sensitive de sktop pc applications. the stac9227/9228/9229/9230 incorporate sigmatel 's proprietary technology to achieve a dac snr in excess of 100 db. the higher performance and quality of sigmatel?s audio solutions brings consumer electronics level performance to the notebook, desktop and media center pc. the stac9227/9228/9229/9230 provide stereo 24-bit, full duplex resolution supporting sample rates up to 192 khz by the dac and adc. the stac 9227/9228/9229/9230 spdif in/out support sample rates of 96 khz, 48 khz and 44.1 khz plus spdif out supports 88.2 khz. additional sample rates are supported by the driver software. the stac9227/9228/9229/9230 support all desired ei ght channel configurations, including switch- able headphone out, and universal jackstm functionality for jack detection and re-tasking. the spdif interface provides connectivity to consum er electronic equipment like dolby digital decod- ers, powered speakers, mini disk drives or to a ho me entertainment system. all analog i/o pairs sup- port line_in, li ne_out and mic. mic inputs can be programmed with 0/10/20/30/40db boost. for more advanced configurations, the stac9227/9228/9229/9230 has up to four general purpose i/o (gpio) pin. the stac9227/9228/ 9229/9230 also provide a single ended cd input for compatibilit y with drm solutions and to support legacy os issues. the stac9227/9228/9229/9230 integrate a headphon e amplifier which is available on ports a, b and d. the headpho ne amplifier is dedicated to these three outputs for increased flexibility, enhanced user experience, and reduced implementation costs. the universal jack capabilities a llow the codecs to detect when audio devices are connected to the codec, and to allow the codecs to be reconfigured to support these devices regardless of which port they are plugged into the system. spdif input sensing is also supported. the fully para- metric sigmatel softeq can be initiated upon headphone jack insertion and removal for protection of notebook speakers. note: the jack detect circuit and component selection are critical for accurate detection of audio jacks on individual ports. pl ease see the sigmatel stac927x reference design for circuit implementation details. the stac9227/9228/9229/9230 operate with a 3.3 v digi tal supply and a 3.3 v to 5 v analog supply. the stac9227/9228/9229/9230 are available in a 48-pin lqfp environmental (rohs) package. stac9227/9228/9229/9230 8-channel high definition audio codec pc audio idt? 8-channel high definition audio co dec

ports g & h do not have vrefout support note 1 : on the stac9227/9228/9229/9230 family, only one function can be selected on each pin pair at a time. for example, a pin pair cannot be conf igured as an input and output at the same time. configuration can be changed at any time. note 2 : three headphones should not be used simultaneously. perf ormance degradation will occur when using two headphones simultaneously. see electrical specif ications for details. note 3 : when the 40db microphone boost feature is e nabled, gain increases greater than 6db may result in significant audio qualit y degradation of the microphone audio input. in particular, when the 40db mic boost is active, the snr, thd+n and dc offset will significantly deg rade regardless of the input signal level. 3.1.1. audio jack presence detect sense_a pin is used to detect the presence of pl ugs in ports a, b, c, and d. sense_b pin is used to detect the presence of plugs in ports e, f, g, ad h. refer to the reference design for port detect circuitry. select the precision of the resistors used as follows: avdd nominal voltage (+-5%) resistor tolerance sense a (if port d is used) resistor tolerance sense a (if port d is not used) resistor tolerance sense b (if port h is used) resistor tolerance sense b (if port h is not used) 5 v1%1%1%1% 4.5 v 1% 1% 1% 1% 4 v 0.50% 1% 0.50% 1% 3.3 v 0.10% 1% 0.10% 1% stac9227/9228/9229/9230 8-channel high definition audio codec pc audio idt?
