HDMI 1.3 mandates single-link bandwidth of 340 MHz, and according to IT6613 spec sheet:
“The IT6613 is a high-performance HDMI transmitter, fully compatible with HDMI 1.3”
Actually, it’s not a surprise that the IT6613 can do much more than 165Mhz since this value is part of the old “standard” and not actual measured value by the manufacturer.
The quality of the HDMI cable is more important at this point if the IT6613 can push 190MHz.
