Product data sheet
The sequence of events related to a host and a peripheral, both with ISP1504x1, is as
follows.
1. High-speed idle: Initially, the host and the peripheral are idle. The host has its 15 k
2. Full-speed suspend: When the peripheral sees no bus activity for 3 ms, it enters the
3. Resume K: When the host wants to wake up the peripheral, it sets OPMODE to 10b
4. High-speed traffic: The host link sets high-speed (XCVRSELECT is set to 00b) and
pull-down resistors enabled (DP_PULLDOWN and DM_PULLDOWN are set to 1b)
and 45

suspend state. The peripheral link places the ISP1504x1 into full-speed mode
(XCVRSELECT is set to 01b), removes 45
pull-up resistor on DP (TERMSELECT is set to 1b). The peripheral link then places
the ISP1504x1 into low-power mode by setting SUSPENDM, causing the ISP1504x1
to draw only suspend current. The host also changes the ISP1504x1 to full-speed
(XCVRSELECT is set to 01b), removes 45
1b), and then may or may not be powered down.
