General Description
The ST7537HS1 is a half duplex asynchronous FSK MODEM designed for home automation communication on the domestic electric mains which complies with the EN 50065-1 CENELEC standard.
It mainly operates from a 10V power supply and a 5V power supply for the microcontroller digital interface.
Key Features
- - An additionnal amplifier allows the observation of the Rx band-pass filter output on pin RxFO. - A direct input to the Tx band-pass filter and to the IF filter (TxIFI) is selected when TEST3 = 1. - The 1 second normal duration of the Tx to Rx mode automatic switching is reduced to 488µs and the 1.5 second watch-dog time out is reduced to 46.3µs when TEST2 = 1. - When TEST1 = 1 the Tx to Rx mode automatic switching is desactivated and the functional mode of the circuit is fully controlled by Rx.
