Product data sheet
1. General description
The NCX8193 is an advanced audio jack accessory detector and controller.
It supports 3-pole and 4-pole connectors and detects the insertion of plugs into jacks
using a fault detection technique. An internal microphone bias line switch allows a codec
or application processor to control the audio jack configuration. The device supports a
broad variety of after-market headphones.

8. Functional description
The simplified schematic of the NCX8193 is shown in Figure 1.
If no plug is inserted, J_DET is pulled-up to VCC via a 1.2 M resistor. Once J_DET is
pulled below 400 mV, the pull-up resistor is switched out and J_DET is connected to a
variable current source. The current source slowly increases its output current. If J_DET
remains lower than 300 mV, DET is set LOW to indicate that a plug has been inserted.
In case DET is set LOW, when EN is HIGH, J_DET is connected to the current source and
the integrated button press detection circuit on J_MIC is active. The button press
detection uses a trigger level of 780 mV. It enables a 1.8 V bias voltage in combination
with an Rbias, matching the series resistance of the microphone, to detect button presses.
Not only call-end button press but also forward and reverse button press event levels can
be passed from J_MIC to MIC. The codec or processor decodes according to the
individual button pressed. Refer to Figure 3 and Figure 4 for details.

9. Application diagram
For stable operation of the NCX8913, place a 4.7 F capacitor between VCC and GND
and place a 1F capacitor between VCC(IO) and GND. These bypass capacitors should be
placed as close to the device as possible with low-ohmic connections from the power
supplies and GND connections.
When the headset or accessory plug is inserted into audio jack, the J_DET pin is shorted
to the left (L) audio channel. Audio performance, within the audio range of 20 – 20 kHz,
may be affected when connecting external circuitry to the J_DET pin.

Rth(j-a) is dependent upon board layout. To minimize Rth(j-a), ensure that all pins have a solid connection to larger copper layer areas. In
multi-layer PCBs, the second layer should be used to create a large heat spreader area below the device. Avoid using solder-stop
varnish under the device.

with the same product type number(s) and title. A short data sheet is intended
for quick reference only and should not be relied upon to contain detailed and
full information. For detailed and full information see the relevant full data
sheet, which is available on request via the local NXP Semiconductors sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
NXP Semiconductors and its customer, unless NXP Semiconductors and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the NXP Semiconductors product is
deemed to offer functions and qualities beyond those described in the
Product data sheet.

Product data sheet
Suitability for use — NXP Semiconductors products are not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept no liability for
inclusion and/or use of NXP Semiconductors products in such equipment or
applications and therefore such inclusion and/or use is at the customer’s own
risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Terms and conditions of commercial sale — NXP Semiconductors
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nxp.com/profile/terms, unless otherwise
agreed in a valid written individual agreement. In case an individual
agreement is concluded only the terms and conditions of the respective
agreement shall apply. NXP Semiconductors hereby expressly objects to
applying the customer’s general terms and conditions with regard to the
purchase of NXP Semiconductors products by customer.
