Wireless responder circuit with transceiver and codecs module
Transmitter circuit is mainly composed of radio transmission header TDC1808 and dedicated coding integrated circuit MC145026, and it is shown in Figure 1. MC145026 encoding manifold's pin function is shown in Figure 2. It consists of the clock oscillator, divider, address/data-encoding input circuit and data selection and buffer. Clock oscillator and divider provide benchmark clock for the whole encoder to coordinate the work of other parts. Address/data-encoding input circuit will enter different addresses and encoding signals converted from data. Data selection and buffer circuit can change parallel code to a serial code and output.
