Data Ready or DT-AS Detection Delayed Steering Output.
This pin is active low. When FSK demodulation is enabled, this pin is the Data Ready output. In FSK interface mode 0,
this pin is unused and reads ‘1’. While in mode 1, this pin is normally high and goes low for half a bit time at the end of
a word. If DCLK starts during DR low, the first rising edge of the DCLK input will return DR to high. In this way, reading
of the first DATA bit can clear the interrupt requested by a low going DR .
When DT-AS detection is enabled, this pin is the Delayed Steering Output. An active low signal on this output indicates
the detection of a ‘guard time qualified’ DT-AS.
DT-AS Early Steering Output.
This pin is an active high output to indicate the detection of a raw DT-AS signal. It is used with the ST/GT pin and
external components to time qualify the detection.
DT-AS Detection Steering Input/Guard Time Output.
It’s a CMOS output and an input of voltage comparator. It is used in conjunction with the EST pin and external
components to time qualify a raw DT-AS signal detection.
If the voltage at this pin is greater than the voltage threshold, DR / STD pin is asserted low to indicate that a DT-AS has
been detected. A voltage less than the threshold enable the device to accept a new DT-AS and return the DR / STD pin
to high.
FSK Carrier Detector or Stutter Dial Tone Detector Output.
This is an active low CMOS output signal to indicate the presence of in-band FSK signal or valid Stutter Dial Tone
signal.
3/5 V Power Supply.
Control Bit 1 (Function Select 1).
This pin is used with CB2 to select FSK demodulation, Tip/Ring DT-AS/Dial Tone detection, Hybrid DT-AS/Dial Tone
detection with or without Stutter Dial Tone Detection. See Table 1. When CB0 is high, CB1 and CB2 pins are both low,
the device is set into the power down state.
Control Bit 2 (Function Select 0).
This pin is used with CB2 to select FSK demodulation, Tip/Ring DT-AS/Dial Tone detection, Hybrid DT-AS/Dial Tone
detection with or without Stutter Dial Tone Detection. See Table 1. When CB0 is high, CB1 and CB2 pins are both low,
the device is set into the power down state.
Gain Select Output of the gain adjustable Hybrid OP amp.
The hybrid receive signal can be amplified or attenuated at GS2 by adjusting the feedback resistor between GS2 and
IN2-. When the CPE is off-hook, DT-AS detection of the GS2 signal should be enabled via the CB1 and CB2 pins.
Inverting Input of the gain adjustable Hybrid OP amp.
Non-inverting Input of the gain adjustable Hybrid OP amp.
