Telegram : @zeusmining_presalesThe signal level conversion chip whose silkscreen is 74GTE7 is located on the S19jpro hash board of the Antminer. U1 is the RST signal level conversion chip, U2 is the RX signal level conversion chip, and U4 is the TX signal level conversion chip. When the 3.3V voltage from the control board is passed through the level conversion chip, it is converted into the 1.8V voltage used by the ASIC chip signal. Among them, the RST signal and the TX signal start from the CPU of the control board, pass through the level conversion chip, and are transmitted from the No. 1 chip to the last chip. The RX signal starts from the last chip, is transmitted to the No. 1 chip, then passes through the level conversion chip and back to the control board's CPU. If the two signal level conversion chips whose silkscreen is 74GTE7 are damaged, it is recommended that you replace the new signal level conversion chips immediately to ensure the normal operation of the S19jpro hash board. We provide you with a high-quality, adequate supply of accessories and tools; welcome to buy.
Notes: The chips of the Antminer S19jpro hash board marked U1, U2, and U4 can be used universally.
SN74AVCH1T45YZPR chip silk screen mark is TE, and the common chip is 74GTE7, 72GTE7, etc.
