Microchip Technology PD81101
The PD81101 and PD81000 chipset is designed to comply with ETSI's TS 101 548 Metallic Detection Startup (MDSU) protocol and supports detection and classification prior to power-up, provides continuous protection from Error Line Conditions (ELC) prior to power-up and afterwards, in accordance with the standard. The RPF chipset provides real-time protection against overload, under-load, over-voltage, short-circuit, foreign DC voltage, and off-hook phone. This chipset allows the CPE host to receive telemetry data through I2C communication of RPF line status.| Part No. | PD81101 |
