Elcodis is a trademark of Elcodis Company Ltd. In receive mode the attenuation as25523 the a2s523 path and the transmit path can be controlled by Register Handsfree receive end gain between 0dB and dB. Specifications Contact Us Ordering Guides. It is recommended to re-write all registers after a line-break, as a line break may take long enough to discharge VDD, even when the MASK bit was set. The register is static, therefore it can be clocked at any speed up to 5MHz.
This guarantees safe operation in case of unexpected loss of power during normal operation. An operating mode with reduced performance is from 5mA to 15mA. As a safety margin however, it is recommended to re-write all registers after a flash Additional settings during line breaks If a line-break-detection brief interruption of the line while in off-hook state is implemented, the same rules apply as for a Flash: There is no LLC for this path.
STMicroelectronics’ two new microcontroller product lines enhance the energy efficiency, functional integration and design flexibility of the STM32F4 basic product line high-end products to meet the technical requirements of high-performance embedded design.

There is LLC for this path. The first four bits 7,6,5,4 are the addresses of the registers, the last four bits 3,2,1,0 are the data bits. The soft clip circuit limits the output voltage at LO to 1. Example of a typical power-up sequence A typical power-up sequence will require the following programming. Applications Enhanced handsfree feature phones with CallerID and extended displays Quickly Enter the access of compare list to find replaceable electronic parts.
Timing The data format for writing to a register has the following form: Rx-offset setting 0 0 0mV 0 1 12mV 1 0 40mV 1 1 mV AS datasheet and specification datasheet Download datasheet.

Want to gain comprehensive data for AS to optimize the supply chain include cross references, lifecycle, parametric, counterfeit risk, obsolescence management forecastsplease contact to our Tech-supports team. This product is intended for use in normal commercial applications.
Re-writing all registers also eases later software updates, as only register contents need to be changed, but no additional command lines need to be inserted.

The information furnished here by austriamicrosystems AG is believed to be correct and accurate. It is therefore recommended to keep these lines short, filter them by a discrete lowpass filter and reduce the clock speed accordingly. For factory test only! The soft clip circuit limits the output voltage at RO to 1V p.
Each register has 4 bit data width. Applications Enhanced handsfree feature phones with CallerID and extended displays. Prev Next Telephone Line Interface and. With an external resistor of approx. This provides a maximum of independence of AC-impedance and side tone from each other. The new type of capacitor has a space-saving design with two, three or even ten identical capacitors connected in parallel on the same terminal to increase the capacitance.
