4-5. Digital Out
There are three Digital Out: the type 1 format for broadcasting stations, the type 2 form 1 format for home
use, and the type 2 form 2 format for the manufacture of software.
The CXD2548R supports type 2 form 1.
Sub Q data which are matched twice in succession after a CRC check are input to the first four bits (bits 0 to
3) of the channel status.
Table 3-2.
3-6. Servo Auto Sequence
This function performs a series of controls, including auto focus and track jumps. When the auto sequence
command is received from the CPU, auto focus, 1-track jump, 2N-track jump and N-track move are executed
automatically.
Servo is used in an exclusive manner during the auto sequence execution (when XBUSY = low), so that
commands from the CPU are not transferred to the servo, but can be sent to the CXD2548R.
Connect the CPU and RF as shown in Fig. 3-3.
When CLOK goes from low to high while XBUSY is low, XBUSY does not become high for a maximum of
100μs after that point. This is to prevent the transfer of erroneous data to the servo when XBUSY changes
from low to high by the monostable multivibrator, which is reset by CLOK being low (when XBUSY is low).
