Application Information
CableCARD" Operating Modes
The OpenCable system has a host component (S-Host
or M-Host) and a card component (S-Card or M-Card).
The host / card combination determines which
operational mode is used i.e. S-Mode or M-Mode. This
in turn determines the appropriate state diagram. Table
3 below shows all of the combinations and operating
modes.

Table 3 Operating Mode Combinations
An M-Host has the choice to accept or not accept an S-
Card. If the M-Host accepts the S-Card then the M-Host
will initiate a change from M-Mode to S-Mode.
Otherwise, the M-Host will not power-up the S-Card.
S-Host
After power-up, the S-Host remains in state 0 [000]
unless one of two events occurs:
1. CIS Request The CableCard" may request
that the Vpp outputs be provided with 5VIN, that
is, enter state 1 [001]. It is the S-Host decision
whether to provide the Vpp outputs with 5VIN.
The S-Host has two possible options.
a. If the S-Host refuses to provide 5VIN,
then the S-Host does not change to
state 1 [001] and will remain in state
0 [000], even upon card removal. See
paragraph 2 below.
b. If the S-Host grants 5VIN, then S-Host
changes to state 1 [001]. The S-Host
remains in state 1 [001] without
returning. See paragraph 2 below.
2. Card removal Upon card removal, the S-Host
has two possible options:
a. The S-Host changes directly to state
0 [000], regardless of the state at card
was removed.
b. The S-Host has the option to pass
through state 6 [110] to remove any
excessive voltage or charge on the Vpp
outputs. The S-Host then returns to
state 0 [000].
Figure 1 shows S-Mode power state diagram.

M-Host
1. Power-up - Upon power-up, M-Host two options:
a. Move directly the state 2 [010]
b. Pass through state 7 [111] to remove any
excess voltage or charge, then move to
state 2 [010]
2. No Card M-Host will remain in state 2 [010]
until card insertion.
3. Card Detection If the M-Host detects that the
inserted card is an M-card, then the M- Host will
change to state 3 [011]. This informs the card
that the host is an M-Host.
4. Card ID The M-Host uses the card
identification process to determine what type of
card it is and what modes the card can operate
in. There are three options:
a. If the card is an M-Card, then the M-
Host will change to state 4 [100] and
remain in state 4 [100] until card
removal.
b. If the card is an S-Card able to support
CH1, then the M-Host will reset the card
and power-up in S-Mode. The card will
remain in S-Mode until card removal.
c. If the card is not an M-Card, or an S-
Card not able to support Ch1, then
power will not be provided to the card.
The card will remain without power and
not change state until card removal.
