PVS8 Hardware Interface Overview 3.2 Power Supply 25 3.2 Power Supply PVS8 needs to be connected to a power supply at the SMT application interface - 6 lines each BATT+ and GND. There are three separate voltage domains for BATT+: • BATT+_PA1 with 2 lines for the first power amplifier supply • BATT+_PA2 with 2 lines for the second power amplifier supply • BATT+ with 2 lines for the general power management.
PVS8 Hardware Interface Overview 3.3 USB Interface 25 3.3 USB Interface PVS8 supports a USB 2.0 High Speed (480Mbit/s) device interface that is Full Speed (12Mbit/s) compliant. The USB interface is primarily intended for use as command and data interface and for downloading firmware. The external application is responsible for supplying the VUSB_IN line. This line is used for cable detection only. The USB part (driver and transceiver) is supplied by means of BATT+.
PVS8 Hardware Interface Overview 3.4 Serial Interface ASC0 25 3.4 Serial Interface ASC0 PVS8 offers an 8-wire unbalanced, asynchronous modem interface ASC0 conforming to ITUT V.24 protocol DCE signalling. The electrical characteristics do not comply with ITU-T V.28. The significant levels are 0V (for low data bit or active state) and 1.8V (for high data bit or inactive state). PVS8 is designed for use as a DCE.

PVS8 Hardware Interface Overview 5 Antenna Interfaces 29 5 Antenna Interfaces 5.1 CDMA Antenna Interface The PVS8 CDMA antenna interface comprises a main CDMA antenna as well as an optional CDMA Rx diversity antenna to improve signal reliability and quality1. The interface has an impedance of 50. PVS8 is capable of sustaining a total mismatch at the antenna interface without any damage, even when transmitting at maximum RF power.
PVS8 Hardware Interface Overview 5.1 CDMA Antenna Interface 29 5.1.1 Antenna Installation The antenna is connected by soldering the antenna pads and their neighboring ground pads directly to the application’s PCB. The distance between the antenna pads and their neighboring GND pads has been optimized for best possible impedance. To prevent mismatch, special attention should be paid to these pads on the application’ PCB.
PVS8 Hardware Interface Overview 5.2 GNSS Antenna Interface 29 5.2 GNSS Antenna Interface In addition to the RF antenna interface PVS8 also has a GNSS antenna interface. The GNSS antenna installation and connector are the same as for the RF antenna interface (see Section 5.1.1). For use with GPS and GLONASS it is recommended to use a GPS and GLONASS capable antenna. It is possible to connect active or passive GNSS antennas. In either case they must have 50 Ohm impedance.
