b3a0347a | 21 | LFAST is a physical communication interface used mainly by the NXP Zipwire |
c5a2f0b4 SA |
22 | interface. It's a framed asynchronous serial interface using differential |
23 | TX/RX pairs, capable of data rates of up to 320 MBit/s. | |
24 | ||
25 | This interface is also provided by Infineon as HSCT. | |
26 | ||
27 | As with most differential signals, it's sufficient to measure TXP or RXP, no | |
28 | need for a differential probe. The REFCLK used by the hardware isn't needed by | |
29 | this protocol decoder either. | |
