Electrical characteristics—LFAST electrical specifications
Formerly named “DigRF interface electrical characteristics”; renamed to “LVDS Fast
Asynchronous Serial Transmission (LFAST) pad electrical characteristics. The change
from “DigRF” to “LFAST” applies throughout.
Figure 16 (LFAST and MSC/DSPI LVDS timing definition). Figure updated.

• Extensive changes throughout table footnotes.
Table 31 (LFAST transmitter electrical characteristics,):
Differential output voltage swing parameter:
• Removed the delta symbol from |VOD|
• Changed Min = 100, Typ = 171, Max = 285. removed the “+/-” from each value.
Rise/Fall time parameter:
• Changed “(10%–90% of swing)” to (absolute value of the differential output voltage
swing
Table 32 (MSC/DSPI LVDS transmitter electrical characteristics ,):
Differential output voltage swing parameter:
• Removed the delta symbol from |VOD|
• Changed Min +/- 150 to 150
• Changed Typ +/- 200 to 214
• Changed Max +/- 400 to 400
Rise/Fall time parameter:
• Changed “(10%–90% of swing)” to (absolute value of the differential output voltage
swing)
Table 33 (LFAST PLL electrical characteristics)
• Changed footnote 2, from “320” to “640” MHz frequency
