Nokia FYGM HDMI Pinout
Signal descriptions:
- GPS_TIME_IN_H, GSM_FC_IN_H, GPS_TIME_IN_L, GSM_FC_IN_L: serial datafrom GPS to CPU or GSM Frame Clock input; RS422/485 differential
- SingleEndedIn: REF2M_IN REF10M_IN Accepts TTL/CMOS and SINE from -6 to+13 dBm. Input impedance is approximately 75 Ohm, Reduced swing TTL resultingfrom TTL-Gate plus 75 Ohm source termination is OK, too.
- NC: No Connection
- GPS_PPS_IN_H, GSM_FN_IN_H, GPS_PPS_IN_L, GSM_FN_IN_L: PPS pulsefrom GPS or GSM Frame Number input; RS422/485 differential
- GPS_CONTROL_H, GPS_CONTROL_L: Serial data form CPU to GPS; RS422/485differential.
- GPS_PWR, GPS_PWR_RET: GPS power supply: 50 mA at 15 to >35 VGPS_PWR_N might not be isolated from GND but cannot be relied upon to be thesame.
