ALC888S & ALC888Sdd datasheet 7.1+2 channel high definition audio codec w/two independent s/pdif-out 71 track id: jatr-1076-21 rev. 1.2 10.2. onboard front panel header connection option 1 in figure 20 comes from by intel?s front pane l io connectivity design guide. a drawback of this option is that the ports connected to the front panel mu st use the same jack detection pin. according to the hd audio standard specification, port s a/b/c/d use ?sense a? as the ja ck detect pin; ports e/f/g/h use ?sense b? as the jack detect pin. this is not a good option when the system integrators want to use port-a (pin 39/41) and port-f (pin 16/17) to be the front panel ports, as ?sense a? and ?sense b? cannot be tied together. option 2 in figure 20 shows an alterna tive front panel header design that is also compatible with standard front panel i/o cable. the option 2 header design lets the two ports use an individual sense pin, and is compatible with current hd audio front panel cable. +3.3vd +3.3vd sense b sense b system gpi system gpi fio-port1-l fio-port1-r fio-port2-r fio-sense fio-sense fio-port2-r fio-port2-l fio-port1-l port2-sense-return port1-sense -return fio-port1-r fio-sense fio-port2-l port1-sense -return port2-sense -return line2-r line2-l mi c2-l front-io-jd mi c2-r fio-presence# line2-jd mi c2-j d mi c2-vr efo line2-r line2-l mi c2-l mi c2-r mic2-vr efo line2-jd mic2-jd presence# presence# r25 20k,1% j5 con10a 1 3 5 7 9 2 4 6 8 10 r26 39.2k,1% r21 4.7k r20 4.7k d5 1n4148 d6 1n4148 c44 1u + c51 100u + c48 100u c46 1u r11 4.7k l17 ferb c49 100p c50 100p l14 ferb l15 ferb c41 100p c42 100p l16 ferb jack 8 fio-port1 (jack-f) 1 2 5 3 4 jack 7 fio-port2 (jack-e) 1 2 5 3 4 r14 10k r23 10k j2 con10a 1 3 5 7 9 2 4 6 8 10 j3 con10a 1 3 5 7 9 2 4 6 8 10 r18 20k,1% d3 1n4148 r19 39.2k,1% c35 1u + c39 100u + c38 100u r12 4.7k d4 1n4148 c37 1u key hd audio front panel i/o cable onboard front panel header key onboard front panel header key option 2: a more flexible front panel header option 1: follow intel's hd audio front panle header design (two ports must be in the same jack detect group) (each port can be in different jack detect group) figure 20. onboard front panel header connection www.datasheet.co.kr datasheet pdf - http://www..net/
