Difference between MST5C26 and MST5C16

Manufacturers produce direct sales LED lamp bead patch lighting products 0805 white light super bright indicator light dedicated

The main chip MST5C16 has low integration, many peripheral devices, and high failure rate. The single indicator light is blue. The lamp will always be on after power-on or standby. It is difficult to adjust the linearity after power-off.

MST5C26 new design, integrated related peripheral devices, improve the reliability of the whole machine. Add 3A optimization based on MST5C16, nine-band equalization, black and white level extension, increase universal lock, hotel mode, etc. use red light, boot process or operate remote controller It will flash, the light will be off after the power is turned on, the light of the light will not affect the user's viewing, and the light will remain on after the standby; the user can always know that the linearity of the machine state is greatly improved, and the sharpness is greatly improved.

Most of the functions of the MST5C16 video decoding block LA76818 are integrated into the MST5C26. The TV part uses the TDA9885 to process the TV audio and video signals. The MST5C26 integrates the original audio processor TDA7439, MCU, SDRAM, SCALER, etc.; 8380 replaces the KA2500, The TDA9116's functionality is also integrated to focus the processing of digital signals on both chips.

The power supply circuit, EMC filter circuit and degaussing circuit of the card reader are reasonably planned on a 247X330mm main board, which avoids the influence of the circuit adapter on the EMC, the internal temperature rise, the wrong insertion and the reverse insertion.
