PulseCore Semiconductor PCS3P2191A
The PCS3P2191A allows significant system cost savings by reducing the number of circuit board layers, ferrite beads, and shielding that are traditionally required to pass EMI regulations. The PCS3P2191A uses the most efficient and optimized modulation profile approved by the FCC and is implemented in a proprietary all digital method.
