RX LED indicators are on when sending samples to the host and off when unable to do so. This means that TX/RX activity LED indicators will blink off in a temporary transmit underflow or receive overflow condition, indicating that the host is not sending or receiving samples fast enough. The host will be notified of the condition and output a "U" or "O" as well. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +External Connections +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Below is a table showing the external connections and respective power information: + +=============== ======================== ======================================================== +Component ID Description Details +=============== ======================== ======================================================== + J601 External Power | 6 V + | 3 A + J701 USB Connector | USB 3.0 + J104 External PPS Input | 1.8 V - 5 V + J101 GPS Antenna | GPSDO will supply nominal voltage to antenna. + J100 External 10 MHz Input | +15 dBm max + J800 RF B: TX/RX | TX power +20dBm max + | RX power -15dBm max + J802 RF B: RX2 | RX power -15dBm max + J803 RF A: RX2 | RX power -15dBm max + J801 RF A: TX/RX | TX power +20dBm max + | RX power -15dBm max +=============== ======================== ======================================================== + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +On-Board Connectors and Switches +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Below is a table showing the on-board connectors and switches: + +=============== ======================== ======================================================== +Component ID Description Details +=============== ======================== ======================================================== + J502* Mictor Connector | Interface to FPGA for I/O and inspection. + J503* JTAG Header | Interface to FPGA for programming and debugging. + J400 Debug Header | Pin 1 - serial data out (115200 8,N,1 @ 1.8V) + | Pin 2 - ground + | Pin 3 - serial data in (not connected) + S100 GPSDO ISP Enable Switch | Not supported + S700 FX3 Hard Reset Switch +=============== ======================== ======================================================== + +\* B210 Only + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Test Points +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Below is a table showing the test points: + +=============== ================================== =================== +Component ID Description Details +=============== ================================== =================== + J603 Upstream Voltage Regulation | 3.3 V supply + Test Point | Pin 1 - 3.7 V + | Pin 2 - gnd + J604 Catalina Supply Test Point | Pin 1 - 1.3 V + | Pin 2 - gnd + J605 FPGA Supply Test Point | Pin 1 - 1.2 V + | Pin 2 - gnd + J606 FX3 Supply Test Point | Pin 1 - 1.2V + | Pin 2 - gnd + J609 Upstream Voltage Regulation | 1.3 V supply + Test Point | Pin 1 - 1.8 V + | Pin 2 - gnd + T600 External Voltage Supply + Test Point + T601 1.3 V Catalina Power Good + Test Point + T602 1.3 V Catalina Synthesizer + Power Good Test Point + TP302 Catalina AUX DAC1 Test Point + TP303 Catalina AUX DAC2 Test Point + T700 Not connected + T701 Not connected + T702 FX3 External Clock In | Not used + T703 FX3 Charger Detect Out +=============== ================================== =================== + + |
