SSS1629 / 3S1629 Description:
SSS1629 / 3S1629 addition to the basic functions of a conventional USB headset chip has, SSS1629-A5 (3S1629) also increases the breathing light / engagement lamp function, composite key function, one-touch EQ cycle, SPDIF OUT, support NEC coded infrared remote control, and supports plug-WM8988 CODEC and other high-end solutions to meet the high-end headphones.
Second, the main features of SSS1629,3S1629:
. 1, SSS1629,3S1629 headphone output
2, SSS1629,3S1629 microphone output
3, a plurality of function keys SSS1629,3S1629 (volume up, volume down, mute playing, recording mute control on the player a / next / pause / stop, EQ, and other user-defined key)
4, a plurality of SSS1629,3S1629 health indicator (playback indicator, indicating the recording mute, the mute play indication, EQ instructions, etc.)
. 5, SSS1629,3S1629 respiratory lamp
6, SSS1629,3S1629 dual input
. 7, the SPDIF OUT SSS1629,3S1629
. 8, the SPDIF OUT
. 9, SSS1629,3S1629 remote control
10, SSS1629,3S1629 an EEPROM may be added to modify the program to implement custom functionality.
Three, SSS1629,3S1629 hardware upgrade of functions:
. 1, SSS1629 / 3S1629 increase breathing lamp, LED lamp lighting effect engagement features:
Brightness SSS1629 / 3S1629 engagement lamps may vary as dB values of music, it may vary according to a fixed rhythm. Each LED PIN drive current of 2mA-16mA; (drive current increases, the higher the power the IC, the more hot recommended 2-4mA). Warring lights, mainly used for gaming headsets, you can display the current intensity of the game. Online control may also be used above, as shown (1-1), adding only an EEPROM (24C02 / 4, etc.) can be realized.
2, lighting effect described SSS1629 / 3S1629 (the breathing light, light war):
A) no music, only do breathing light effect
B) when there is music, LED will change with the amplitude of the music, the display effect lights warring
C) can support up to six separate LED (order. 6); (may be employed in parallel, more LED drivers)
D) lights breathing, engaged around the lamp may be displayed separate audio channels, each occupying three LED lights; may be 6 about the common LED lights. It may be multi-channel parallel, for example: 2 to 12 and the lamp, and 3 to 18 lamps.
An increased respiratory products exemplary lamp button "Insert FIG
. 3, SSS1629 / 3S1629 support and multifunctional composite key consisting of a combination of: for each key by four different methods, from the key functions can be defined, for example, corresponding to: Short Click achieve volume increases, short double-realization control the player jumps on one, a short play to achieve a long silence, long press to achieve recording mute function. in this game you can make mold headset design is more compact, more comprehensive, even old old die four keys, may also be multi-key function.
[Description] SSS1629A5 can define composite keys 4; each compound has four key press method; according to each method may correspond to the 10 kinds of keys function.
A) is used as a single complex key kEY press method (4 types)
A, a short click
b, short double-
c, press
d, a short and a long
B) of the following ten keys, can be user-defined composite KEY press method; (each key can be freely combined, a maximum of four function keys, the need to add setting EEPROM, EEPROM CODE provided by the original). FIG follows (1-2) shown in 
the inset of FIG. 2 the custom key
4, SSS1629 / 3S1629 single 3D Sound button: adjust the 3D sound is nonlinear, such as to modify, required of a professional person to actual requirements and do actually call the effect adjustment.
5, SSS1629 / 3S1629 support / SPDIF OUT: This is the main dispute Soundbar speaker for recording and high-end market with.
6, SSS1629 / 3S1629 NEC support the IR remote control, an NEC encoding specifications, this function is mainly used in the above speaker, controls all key functions. Or through customer-specific software development, achieve specific functional requirements.
7, SSS1629 / 3S1629 output power controlled size: 3S1629 output power of 14mW-22mW may be selected, SNR raised to 86dB, greatly enhance the sound quality. Record pure, no popo sound, the current sound. The size of the output power may be selected or pulled down of IC 22 PIN, or EEPROM is set to achieve.
8, SSS1629 / 3S1629 support one-touch EQ circulation. Before our SSS1629A3 and ISxxx, CM6400, etc. are chosen to stalk switch mode. Now SSS1629A5 with EEPROM can customize the multi-stage EQ sound for product selection, as long as it is large enough EEPROM can store an unlimited period EQ sound. We each segment consisting of five dB value EQ band, chosen embodiment shown in (1-3) below: specific operation, mainly to five dB band values to generate a Bin file, the Bin file into the inside of the EEPROM you can select the sound Bin file. (Supporting projects to modify the software)

9, SSS1629 / 3S1629 high-end USB headset solution: You can plug by IIS WM8988 CODEC and CS4270 high-end, direct drive CODEC initialization, no external MCU drive, USB headset as a high-end solution. To improve the overall sound quality of the selected CODEC standard, far less than the entire BOM COST CM64XX.
Four, SSS1629 / 3S1629 free driver software
the traditional virtual 7.1 software, compatibility with different platforms, less stable. We currently have a free installation, free driver, combined with SSS1629 / 3S1629 hardware EQ \ Software 3D capabilities. The software can be used directly to adjust EQ, 3D capabilities, and online download to a USB headset, permanently stored on the hardware (stored in EEPROM). Customers can modify the interface. Software interface is shown in the demo (2-1,2,3,4,5) as shown:
insert 3 demo software interface is shown in Figure 3-1,5 Zhang
V. custom SSS1629 / 3S1629 virtual 7.1 software
this regard if your company after test-related functions Demo board SSS1629A5, I feel our hardware function right, I can learn and original coordination, communication and detailed virtual 7.1 software approach. You may need to time your company's personnel arrangements and original time to discuss the practice with the specific requirements of the tripartite agents.
