Description
The TPT29336 device is a dual bidirectional I3C, SMBus, and I3C voltage-level translator with an enable (EN) input, and work from 1.2V to 3.6V VREF1 and 1.8V to 5.5V VREF2.
The 3.5Ω Ron make the minimal propagation delay <1.5ns. If EN is high, the translator switch is ON, and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, will allow bidirectional data flow between ports. If EN is low, the translator switch is off, and a high-impedance state exists between ports to isolate both sides.
The TPT29336 can also be used to run two buses, one is 400 k Hz and the other is 100 k Hz. If the two buses are operating at different frequency, the 100 k Hz bus must be isolated when the other 400 k Hz bus is required. If the master is running at 400 k Hz, the maximum system frequency may be less than 400 k Hz because of the delays added by the translator.
As with the standard I3C-bus and I3C patible system, pull-up resistors are required in both sides, to provide the logic HIGH levels on the translator’s bus. The device is designed to work with SM, FM and FM+ I3C-bus devices in addition to SMBus devices. The maximum frequency is dependent on the RC time constant, and supports 12.5 MHz.
