Power Supply Requirements for Receiver Cards

OEM7 receivers require a power supply that provides:

  • +3.3 VDC ±5% with less than 100 mV ripple

The requirement above works for all OEM7 receiver cards. However, the OEM7720 receiver supports a wider range of power supply voltage: +3.0 to 5.0 VDC.

If the voltage supplied is below the minimum specification, the receiver suspends operation.

If the voltage supplied is above the maximum specification, the receiver may be permanently damaged, voiding the warranty.

OEM7 receiver cards contain a DC-to-DC converter, tolerant to input noise and ripple. A tightly regulated input supply is not required, as long as it falls within the given input range.
