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
  • 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

Dai un'occhiata a cosa fa funzionare questi pixel:

Ricevitore bus Texas Instruments SN74LVC8T245 a 8-bit dual-supply

Generatore programmabile di tensioni Texas Instruments BUF16821 e calibratore Vcom

Controller timing Parade Technologies DP665 LCD (lo stesso trovato nell'iMac 4K della scorsa generazione)

Pensiamo questa sia una versione modificata da Apple del DP663

Riduttore sincrono Texas Instruments TPS54218 da 4.5 V a 17 V in ingresso, 2 A SWIFT

Riduttore sincrono Texas Instruments TPS54320 da 4.5 V a 17 V in ingresso, 3 A SWIFT

Texas Instruments TPS65168 LCD bias ad alta risoluzione e completamente programmabile
