APPENDIX G. POWER SUPPLY
Appendix G provides information on the current requirements of the
RCM5700/RCM6700, and includes some background on the chip
select circuit used in power management.
G.1 Power Supplies
The RCM5700/RCM6700 requires a regulated 3.15 V – 3.45 V DC power source. The MiniCore
design presumes that the voltage regulator is on the user board, and that the power is made avail-
able to the RCM5700 board through the edge connectors.
An RCM5700 with no loading at the outputs operating at 50.0 MHz typically draws 130 mA. An
RCM6700 with no loading at the outputs operating at 187.5 MHz typically draws 75 mA.
