87 / 106 page ![]() MPC5634M Microcontroller Data Sheet, Rev. 8 Freescale Semiconductor 87 4.9.2 LVDS pad specifications LVDS pads are implemented to support the MSC (Microsecond Channel) protocol which is an enhanced feature of the DSPI module. The LVDS pads are compliant with LVDS specifications and support data rates up to 50 MHz. Table 22. VRC33 pad average DC current 1 1 These are typical values that are estimated from simulation and not tested. Currents apply to output pins only. Pad Type Symbol C Period (ns) Load2 (pF) 2 All loads are lumped.
