Internal VCO control phase comparator output.
Internal VCO ground. This pin must be connected to 0V.
PLL circuit pins
PDO output current adjustment resistor connection.
Internal VCO power supply.
VCO frequency range adjustment.
Digital system ground. This pin must be connected to 0V.
Slice level control pins
EFM signal output.
EFM signal input.
Test input. This pin must be connected to 0V.
Disc motor control output. This is a 3-value output.
Track detection signal input. This is a Schmitt input.
Tracking error signal input. This is a Schmitt input.
Tracking off output.
Tracking gain switching output. A low level output raises the gain.
