  • Take a peek at what powers those popping pixels:

  • Texas Instruments SN74LVC8T245 8-bit dual-supply bus transceiver

  • Texas Instruments BUF16821 programmable gamma-voltage generator and Vcom calibrator

  • Parade Technologies DP665 LCD timing controller (the same found in the last generation iMac 4K)

  • We assume this is an Apple modified version of the DP663

  • Texas Instruments TPS54218 4.5 V to 17 V input, 2 A synchronous step-down SWIFT converter

  • Texas Instruments TPS54320 4.5 V to 17 V input, 3 A synchronous Step-Down SWIFT converter

  • Texas Instruments TPS65168 high resolution, fully programmable LCD bias

Wirf einen Blick auf das, was die Pixel aufblitzen lässt:

Texas Instruments SN74LVC8T245 8-bit Zweifach Bus Transceiver

Texas Instruments BUF16821 Programmierbarer Gamma-Spannungsgenerator und Vcom Kalibrator

Parade Technologies DP665 LCD Zeitkontroller (der gleiche wie in der letzten Generation von 4K iMacs)

Wir vermuten eine von Apple modifizierte Version des DP663

Texas Instruments TPS54218 Eingang 4.5 V bis 17 V, 3 A synchron SWIFT Abwärtswandler

Texas Instruments TPS54320 Eingang 4.5 V bis 17 V , 3 A synchron SWIFT Abwärtswandler

Texas Instruments TPS65168 hochauflösender, voll programmierbarer LCD Versorger
