2.15Audio AC'97 Link interfaces (CN4)
The PCM-9587 is equipped with a high quality audio interface, which provides 16-bit CD-quality recording and playback as well as OPL3 compatible FM music. It is sup- ported by all major operating systems and is completely compatible with Sound Blaster Pro.
2.15.1Audio connector(CN4)
The PCM-9587 provides all major audio signals on a 16-pin flat-cable connector, CN4. The audio signals include Microphone in (mono), Line in (stereo), Line out (ste- reo) and Speaker out (stereo). You will need an adapter cable if you use traditional jack connectors for these audio signals.
2.15.2CD audio-in connector (CN3)
All CD-ROM drives can provide analog audio signal output when used as a music CD player. The CN3 on PCM-9587 is a connector to input CD audio signal into the audio controller. The audio cable of your CD-ROM drive will be used to connect to CN3.
2.16COM port connector (CN21)
The PCM-9587 provides four RS-232 serial ports (COM1,3,4:RS-232, COM2: RS- 232/422/485) in one COM port connector. The COM port connector is a 40-pin, 20*2P 180D(M) 2.0mm, connector. It provides connections for serial devices (a mouse, etc.) or a communication network. You can find the pin assignments for the COM port connector in Appendix C. COM2 can be configured to operate in RS- 232,RS-422, or RS-485 mode. This is done via J5.
2.17VGA/LVDS interface connections (CN7, CN8,CN9)
The PCM-9587’s AGP SVGA interface can drive conventional CRT displays and is capable of driving a wide range of LVDS flat panel displays. The board has three con- nectors to support these displays: one for standard CRT VGA monitors, one for LVDS type LCD panels and one for DVI type LCD panels.
2.17.1CRT display connector (CN7)
CN7 is a 16-pin, dual-inline header used for conventional CRT displays. A simple one-to-one adapter can be used to match CN7 to a standard 15-pin D-SUB connec- tor commonly used for VGA. Users can drive a standard progressive scan analog monitor with pixel resolution up to 1600 x 1200 at 85 Hz and up to 2048 x 1536 at 75 Hz. Pin assignments for CRT display connector CN7 are detailed in Appendix B.
2.17.2LVDS LCD panel connector (CN8)
The PCM-9587 uses the Intel 852 GM chipset that supports single- or dual-channel LVDS panel up to UXGA panel resolution with frequency range from 15MHz to 112MHz.
The PCM-9587 supports single or dual-channel LVDS panels up to UXGA panel res- olution with frequency range from 25MHz to 112MHz. The display mode can be 2 channel (2 x 18bit) LVDS LCD panel displays, or optional (2 x 24bit) LVDS LCD panel display. Users can connector to either an 18, 24, 36 or 48bit LVDS LCD with CN8
