Data PLL Interface
5
VBDPLL
Analog Output
Reference voltage.
6
PLLVSS
Anlog Ground
Ground pin for data PLL and related analog circuitry.
7
LPIO
Analog Output
The output of VCO integrator.
8
LPIN
Analog Input
The negative input terminal of VCO integrator.
9
LPFO
Analog Output
The output of loop filter amplifier.
10
LPFN
Analog Input
The negative input terminal of loop filter amplifier.
11
IREF
Analog Input
Current reference input. It generate reference current for data PLL.
Connect an external 15K resistor to this pin and PLLVSS.
12
PDO
Analog Output
Phase comparator output. Output the phase difference of EFM and
Pck. Sink or (source) a constant current to loop filter over this pin
when phase difference occurs. Otherwise, this pin is high
impedance.
13
PLLVD D
Analog Power(5V)
Power for data PLL and related analog circuitry.
14
DVDD5
Power (5V)
Power pin for analog digital circuitry.
18
DGND
Ground
Ground pin for analog digital circuitry.
Decoder Interface
15
TRON
TTL output, 4mA
Seeking On, active high
16
ASDAT A
TTL input
High Audio serial data input,
17
ALRCK
TTL input
High Audio serial LR input.
19
ABCK
TTL input
High Audio serial bit clock input.
20
EXCK
TTL I/O output ,4mA
Subcode data clock. This clock is used for reading/writing
subcode data out through SBSO pin.. Default is output.
21
SBSY
TTL output, 4mA
Subcode block sync signal. This pin is high when S0 and S1 is
detected.
22
WFCK
TTL output, 4mA
