Features

* es for the selected mode. (See Tables 1 and 2 and Figures 4c and 4d. ) When LB is connected to analog ground (VAG), the modulator generates an echo cancellation tone of 2100 Hz for MC145442B CCITT V.21 and 2225 Hz for MC145443B Bell 103 systems. For normal operation, this pin should be at a logic low

Applications

* Information. ) TxD Transmit Data (Pin 11) Binary information is input to the transmit data pin. Data entered for transmission is modulated using FSK techniques. A logic high input level represents a mark and a logic low represents a space (see Table 1). TxA Transmit Carrier (Pin 17) This is the outpu
