266X CompactFlash Card

Ultra DMA Electrical Requirements

¾Host and Card signal capacitance limits for Ultra DMA operation

The host interface signal capacitance at the host connector shall be a maximum of 25 pF for each signal as measured at 1 MHz. The card interface signal capacitance at the card connector shall be a maximum of 20 pF for each signal as measured at 1 MHz.

¾Series termination required for Ultra DMA operation

Series termination resistors are required at both the host and the card for operation in any of the Ultra DMA modes. Table 13 describes typical values for series termination at the host and the device.
