RF Connectors

Both RF connectors are MMCX RIGHT ANGLE PCB JACK, THROUGH HOLE/AMPHENOL/908-24100.

J100 is GPS/GLONASS antenna input connector. The central pin of this connector supplies +5V voltage for LNA (or up to +20V if an external voltage is applied to the B4 pin of the J481 connector) with sourced current up to 0.2A.

J600 is External Reference Frequency connector. Analog reference clock input (0.5Vp-p to 3Vp-p, 5/10/20MHz) after reset. This input can be configured as output for 20 MHz internal reference oscillator (sine wave, 1Vp-p @ 50 Ohm load).
