It can be calculated by the following equation: 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.

It’s a community-based project which helps to repair anything. Side Tone A good side tone cancellation can be achieved by using the following equation: One can adapt side tone without changing the ACimpedance.

The user can also change the gain via Register Handsfree receive end gain See section “Handsfree”.

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. 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. This product is intended for use in normal commercial applications.

It is therefore recommended to keep these lines short, filter them by a discrete lowpass filter and reduce the clock speed accordingly.

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.

No Conf Tone This gain can be changed by programming from —7. Example of a typical power-up sequence A ss2523 power-up sequence will require the following programming.

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: The soft clip circuit limits the output voltage as223 LS to 2V p.

Applications Enhanced handsfree feature phones with CallerID and extended displays The first ax2523 bits 7,6,5,4 are the addresses of the registers, the last four bits 3,2,1,0 are the data bits. Each register has a default setting see data sheetwhich xs2523 set after power-up of the chip.

The soft clip circuit limits the output voltage at Dahasheet to 1V p. This provides a maximum of independence of AC-impedance and side tone from each other.
