AGC AMPLIFIER INPUTS: Differential AGC amplifier input pins.

ANALOG INPUTS FOR DATA PATH: Differential analog inputs to data
comparators, full-wave rectifier, and servo demodulator.
ANALOG INPUTS FOR CLOCK PATH: Differential analog inputs to the clock
comparator.
PWRDN MODE CONTROL: TTL compatible power control pin. Assertion shuts
down all circuitry, except the serial port. Deassertion and the appropriate bit set
in PD register shuts down the selected circuitry. Active low.
HOLD DATA AGC CONTROL INPUT: TTL compatible power control pin.
Assertion disables the AGC charge pump and holds the input AGC amplifier
gain. Active low.
HOLD DATA AGC CONTROL INPUT: TTL compatible control pin. Assertion
disables the SERVO charge pump. Active low.
SERVO REFERENCE .VOLTAGE INPUT: This voltage is set to half of the Vcc
PULSE DET voltage
LATCH CONTROL INPUT: TTL compatible input. Switcheschannel A into
peak acquisition mode when low. Cap voltage doesn’t change when high.
LATCH CONTROL INPUT: TTL compatible input. Switcheschannel B into
peak acquisition mode when low. Cap voltage doesn’t change when high.
RESET CONTROL INPUT: TTL compatible input. Enables the discharge of
channel A & B hold capacitors when asserted. Active low.
FILTER SIGNAL INPUTS: Self biased differential input signals to active filter.

REFERENCE FREQUENCY INPUT: TTL input. Pin REFERENCE FIN has an
internal pull up resistor. In the test mode, when frequency synthesizer is
bypassed, the REFERENCE FIN frequency requiredis 3 times the data rate.
REFERENCE FIN may be driven by a direct coupled TTL signal.
WRITE DATA NRZ INPUT. TTL input. Connected to the READ NRZ OUTPUT
pin to form a bidirectional data port. Pin WRT DATA NRZ IN has an internal
pull up resistor.
READ GATE : See clocks and Modes.
WRITE CLOCK: TTL input Write mode clock. Must be synchronous with the
Write Data NRZ input. For short cable delays, WRITE CLOCK may be
connected directly to pin READ REF CLOCK. For long cable delays,WRITE
CLOCK should be connected to a READ REF CLOCK return line matched to
the NRZ data bus line delay.
WRITE GATE: TTLinput. Enables the write mode.See Clocks and Modes.
SERVO GATE: TTL input. Enables the servo read mode. Active low.
