LC72720, 72720M
Caution: The output indicates the synchronization state for the previous block.
Mode (PT2 = 0)
The SYNC pin
0 to 2
When synchronized: Low (0). When unsynchronized: High (1)
When synchronized: Goes high for a fixed period (421 μs) at
the start of a block and then goes low.
When unsynchronized: High (1)
3
When PT2 = 0
The RDS-ID pin
No RDS
High (1)
RDS present
Low (0)
10. Test mode settings (4 bits): TS0 to TS3
Initial values: TS0 = 0, TS1 = 0, TS2 = 0, TS3 = 0
(Applications must set these bits to the above values.)
Notes: The T1 and T2 pins (pins 7 and 8) are related to test mode as follows:
The T1 pin must be tied to V
SS
(0 V).
Initial values: CT0 = 0, CT1 = 0
Pin T1
Pin T2
LSI operation
Notes
0
0
Normal operating mode
These states are user settable
0
1
Standby mode (crystal oscillator stopped)
1
0/1
LSI test mode
Users cannot use this state
11. Circuit control (2 bits): CT0 and CT1
RDCL/RDDA/RSFT and ERROR/CORREC/SYNC Output Timing
Timing 1 (modes 1 to 3, PT2 = 0)
Timing 2 (mode 3, PT2 = 0)
Item
Control
CT0
RSFT control
When set to 1, soft-decision control data (RSFT) is easier to generate.
CT1
RDS-ID detection condition
When set to 1, the RDS-ID detection conditions are made more restrictive.

Note: When PT2 = 0, RDDA and RSFT must be
aquired on the falling edge of RDCL.
