SCT2400HDA

Product Description

SCT2400 is a highly integrated RF transceiver and baseband chip for low-power, long range voice communications. The SCT2400 features a 2.4GHz band radio transceiver, supporting ultra-long-distance communication and strong anti-interference capabilities. The SCT2400 also integrates a voice and data transmission baseband core to handle the entire baseband processing. Interfacing to an external audio codec (ADC and DAC), it provides a complete physical and data link layer solution complying with Sicomms Digital Family Radio (DFR) digital voice protocol, and most of the call control layer features. The DFR digital voice protocol is a proprietary digital voice protocol developed by Sicomm for the 2.4GHz band.

The SCT2400 connects to an external audio codec via a high speed I2S port for voice data and I2C for control. Additional UART and USB ports provide user interfacing, including support for customer programming.

The SCT2400 includes a power management control module (built-in LDO). The typical operating voltage in the SCT2400 is 3.3V, and the typical I/O interface operating voltage is also 3.3V. The SCT2400 is supplied in a 10 mm x 10 mm, 0.8 mm pitch BGA 144 package.
