7. input voltage of 3 7 to 5 25VDC to maintain regulation but can also accept down to 3 3VDC in which regulation is bypassed This is useful for battery operated applications Note that an input voltage below 4 75VDC is outside of rated specifications and thus not supported by Janus Note The regulator input is capable of withstanding 6VDC Maximum This is outside the recommended operating voltage of the Plug In modules but but is helpful to know when designing input transient circuitry Plug In Module Input Supply Requirements The current values are given in average units due to the pulsed nature of the transmission scheme It is recommended that your supply source the full peak current value of the transmission pulse in order to maintain proper cellular operation The use of bulk output capacitors on your supply allows for a less powerful supply 4 3 Audio Interface 4 3 1 HSPA910CF The 910CF modules use a DVI audio interface which will not work with the analog audio inerface of the other Terminus Plug In modems The HSPA910CF supports both 12S and PCM master and slave modes and can use a CODEC to convert the interface to analog Below is a block diagram based on DVI and the max 9867 CODEC with GPIO 9 and 10 being used for I2C control of the CODEC Please refer to the referenced DVI Application Notes for full information and example schematics utilizing the MAX9867 Audio CODEC SDA SCL BitClock Word Alignment lt gt
