–24 V @ 50 mA and –70 V @ 60 mA
NOTE: See sheet 11 in the schematics for power supply circuits.
A switching flyback circuit from the 12-V source generates the –24 V and the
–70 V. These outputs are routed to the Am186CC microcontroller router reference
design and are used in the POTS interface.
–5 V @ 200 mA
NOTE: See sheet 11 in the schematics for power supply circuits.
A 5-V buck-boost switching circuit from the 12-V source generates the –5 V. This
power supply provides power to the Am79C031 DSLAC.
