Pin Numbers Symbol Type Description
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.

Decoder Interface
15 TRON TTL output, 4mA Seeking On, active high
16 ASDATA 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.
