1
IN+
Non-inverting Op-Amp (Input).
2
IN-
Inverting Op-Amp (Input).

CAP
Voltage Reference (Output).
Nominally V

. This is used to bias the op-amp inputs.
Capacitor.
Connect a 0.1

OSC1
Oscillator (Input).
Crystal connection. This pin can be driven directly from an external
clocking source.

OSC2
Oscillator (Output).
Crystal connection. When OSC1 is driven by an external clock, this pin
should be left open.

DCLK
3-wire FSK Interface: Data Clock (CMOS Output/Schmitt Input).
In mode 0 (MT88E41
compatible mode - when the MODE pin is logic low) this is a CMOS output which denotes the
nominal mid-point of a FSK data bit.
In mode 1 (when the MODE pin is logic high) this is a Schmitt trigger input used to shift the
FSK data byte out to the DATA pin.
Power supply ground.

DATA
3-wire FSK Interface: Data (CMOS Output).
In mode 0 (MT88E41 compatible mode - when
the MODE pin is logic low) the FSK serial bit stream is output to DATA as demodulated. Mark
frequency corresponds to logical 1. Space frequency corresponds to logical 0.
In mode 1 (when the MODE pin is logic high) the start and stop bits are stripped off and only
the data byte is stored in a 1 byte buffer. At the end of each word signalled by the DR pin, the
microcontroller should shift the byte out to DATA pin by applying 8 read pulses at the DCLK pin.
11
DR
3-wire FSK Interface: Data Ready (Open Drain/CMOS Output).
Active low. In mode 0
(MT88E41 compatible mode - when the MODE pin is logic low) this is an open drain output. In
mode 1 (when the MODE pin is logic high) this is a CMOS output.
This pin denotes the end of a word. Typically, DR is used to interrupt the microcontroller. It is
normally hi-Z or high (modes 0 and 1 respectively) and goes low for half a bit time at the end of
a word. But in mode 1 if DCLK begins during DR low, the first rising edge of the DCLK input
will return DR to high. This feature allows an interrupt requested by DR to be cleared upon
reading the first DATA bit.
12
CD
Carrier Detect (Open Drain/CMOS Output).
Active low. In mode 0 (MT88E41 compatible
mode - when the MODE pin is logic low) this is an open drain output. In mode 1 (when the
MODE pin is logic high) this is a CMOS output.
A logic low indicates that a carrier has been present for a specified time on the line. A time
hysteresis is provided to allow for momentary discontinuity of carrier. The demodulated FSK
data is inhibited until the carrier has been detected.
13
PWDN
Power Down (Schmitt Input).
Active high. Powers down the device including the input
op-amp and the oscillator. Must be low for operation.
