Caution: Handling CMOS Devices These devices contain circuitry to protect the inputs against damage due to high static voltages. However, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltage. An unterminated input can acquire unpredictable voltages through coupling with stray capacitance and internal cross talk.
Both power dissipation and device noise immunity degrades. Therefore, all inputs should be connected to an appropriate supply voltage.
Input signals should never exceed the voltage range from 0.5V or more negative than GND to 0.5V or more positive than VDD. This prevents forward biasing the input protection diodes and possibly entering a latch up mode due to high current transients.
CX11250 Modem operation, including dialing, call progress, telephone line interface, telephone handset interface, PDC HighSpeed/GSM interface, voice/speakerphone interface, and host interface functions are supported and controlled hrough the V.250, V.251, and V.253-compatible command set.
CX11250 modem hardware connects to the host processor via a PCI/Mini PCI bus interface. The OEM adds a crystal circuit,
EEPROM, DIB and LSD power rectifier and filter components, telephone line interface, optional telephone handset interface, optional PDC high speed/GSM interface, optional voice/speakerphone interface, and other supporting iscrete components as required by the modem model and the application to complete the system.
