Interface Logic Signal Levels - IBM DTTA-351010 - Deskstar 10.1 GB Hard Drive Specifications

DSTROBE (Ultra DMA)
This signal is used only for Ultra D M A data transfers between host and drive.
DSTROBE is the data int strobe signal from the device for an Ultra D M A data in transfer.
Both the rising and falling edge of DSTROBE latch the data from DD(15:0) into the host.
The device may stop toggling DSTROBE to pause an Ultra D M A data in transfer.
Note : The termination resistors at the device side are implemented as follows :
Device Termination (implemented on H D D side)
33 ohm for DD0 thru DD15, DMARQ, INTRQ
82 ohm for -CS0, -CS1, DA00, DA01, DA02, -DIOR, DIOW, -DMACK
22 ohm for IORDY
