NOTES:
1. FL1 and FL2 are 455 kHz ceramic bandpass filters, which should
have input and output impedances of 1.5 kΩ to 2.0 kΩ. Suggested
part numbers are MuRata CFU455X or CFW455x – the ‘X’ suffix
denotes bandwidth.
2. LC1 is a 455 kHz LC resonator. Recommended part numbers are
Toko America RMC2A6597HM or 5SVLC–0637BGT (smaller).
The evaluation board layout shown provides for use of either
resonator. Ceramic discriminator elements cannot be used with
the MC3374 due to their low input impedance. The damping
resistor value can be raised to increase the recovered audio or
lowered to increase the quadrature detector’s bandwidth and
linearity – practical limits are approximately 27 kΩ to 75 kΩ.
Typically the quadrature detector’s bandwidth should match the
low IF filter’s bandwidth.
3. The data buffer is set up as a low–pass filter with a corner
frequency of approximately 200 Hz. The audio buffer is a
bandpass filter with corner frequencies of 300 Hz and 3.0 kHz.
The audio amplifier provides bass suppression.
Audio
Output
4. CC1 and CC3 are RF coupling capacitors and should have ≤ 20 Ω
impedance at the desired input and oscillator frequencies.
5. CC2 provides “light coupling” of the oscillator signal into the mixer,
and should have a 3.0 kΩ to 5.0 kΩ impedance at the desired
local oscillator frequency.
6. Capacitors labelled CB are bypass capacitors and should have
20 Ω impedance at the desired RF and local oscillator frequencies.
7. The network of L1, C1 and C2 provides impedance matching of
the mixer input (nominally 3.0 kΩ shunted by 9.0 pF) to 50 Ω at the
desired RF/IF input frequency. This will allow for bench testing of
the receiver from typical RF signal generators or radio service
monitors, but additional or different matching will be required to
maximize receiver sensitivity when used in conjunction with an
antenna, RF preamplifier or mixer.

MC3374
The MC3374 is an FM narrowband receiver capable of
operation to 75 MHz. The low voltage design yields low
power drain and excellent sensitivity in narrowband voice
and data link applications. In the typical application the mixer
amplifies the incoming RF or IF signal and converts this
frequency to 455 kHz. The signal is then filtered by a 455 kHz
ceramic filter and applied to the first intermediate frequency
(IF) amplifier input, before passing through a second ceramic
filter. The modulated IF signal is then applied to the limiting IF
amplifier and detector circuitry. Modulation is recovered by a
conventional quadrature detector. The typical modulation
bandwidth available is 3.0 to 5.0 kHz.
Features available include buffers for audio/data
amplification and active filtering, on board voltage regulator,
low battery detection circuitry with programmable level, and
receiver disable circuitry. The MC3374 is an FM utility
receiver to be used for voice and/or narrowband data
reception. It is especially suitable where extremely low power
consumption and high design flexibility are required.
APPLICATION
The MC3374 can be used as a high performance FM IF for
the use in low power dual conversion receivers. Because of
the MC3374’s extremely good sensitivity (0.6 µV for 20 dB
(S+N/N, see Figure 3)), it can also be used as a stand alone
single conversion narrowband receiver to 75 MHz for
applications not sensitive to image frequency interference.
An RF preamplifier will likely be needed to overcome
preselector losses.
The oscillator is a Colpitts type which must be run under
crystal control. For fundamental mode crystals choose
resonators, parallel resonant, for a 32 pF load. For higher
frequencies, use a 3rd overtone series mode type. The coil
L2 and RD resistor are needed to ensure proper operation.
The best adjacent channel and sensitivity response occur
when two 455 kHz ceramic filters are used, as shown in
Figure 1. Either can be replaced by a 0.1 µF coupling
capacitor to reduce cost, but some degradation in sensitivity
and/or stability is suspected.
The detector is a quadrature type, with the connection
from the limiter output to the detector input provided
internally. A 455 kHz LC tank circuit must be provided
externally. One of the tank pins (Pin 8) must be decoupled
using a 0.1 µF capacitor. The 56 kΩ damping resistor (see
Figure 1), determines the peak separation of the detector
(and thus its bandwidth). Smaller values will increase the
separation and bandwidth but decrease recovered audio and
sensitivity.
The data buffer is a noninverting amplifier with a nominal
voltage gain of 2.7 V/V. This buffer needs its dc bias
(approximately 250 mV) provided externally or else
debiasing will occur. A 2nd order Sallen–Key low pass filter,
as shown in Figure 1, connecting the recovered audio output
to the data buffer input provides the necessary dc bias and
some post detection filtering. The buffer can also be used as
an active filter.
6
The audio buffer is a noninverting amplifier with a nominal
voltage gain of 4.0 V/V. This buffer is self–biasing so its input
should be ac coupled. The two buffers, when applied as
active filters, can be used together to allow simultaneous
audio and very low speed data reception. Another possible
configuration is to receive audio only and include a
noise–triggered squelch.
The comparator is a noninverting type with an open
collector output. Typically, the pull–up resistor used between
Pin 14 and VCC is 100 kΩ. With RL = 100 kΩ the comparator
is capable of operation up to 25 kHz. The circuit is
self–biasing, so its input should be ac coupled.
The regulator is a 1.07 V reference capable of sourcing
3.0 mA. This pin (Pin 17) needs to be decoupled using a
1.0 – 10 µF capacitor to maintain stability of the MC3374.
All three VCCs on the MC3374 (VCC, VCC2, VCC3) run on
the same supply voltage. VCC is typically decoupled using
capacitors only. VCC2 and VCC3 should be bypassed using
the RC bypasses shown in Figure 1. Eliminating the resistors
on the VCC2 and VCC3 bypasses may be possible in some
applications, but a reduction in sensitivity and quieting will
likely occur.
The low battery detection circuit gives an NPN open
collector output at Pin 20 which drops low when the MC3374
supply voltage drops below 1.2 V. Typically it would be pulled
up via a 100 kΩ resistor to supply.
The 1.2 V Select pin, when connected to the MC3374 supply,
programs the low battery detector to trip at VCC < 1.1 V. Leaving
this pin open raises the trip voltage on the low battery detector.
Pin 15 is a receiver enable which is connected to VCC for
normal operation. Connecting this pin to ground shuts off
receiver and reduces current drain to ICC < 0.5 µA.

LEAD AND IS COINCIDENT WITH THE LEAD WHERE
THE LEAD EXITS THE PLASTIC BODY AT THE
BOTTOM OF THE PARTING LINE.
4. DATUMS -A-, -B- AND -D- TO BE DETERMINED AT
DATUM PLANE -H-.
5. DIMENSIONS S AND V TO BE DETERMINED AT
SEATING PLANE -C-.
6. DIMENSIONS A AND B DO NOT INCLUDE MOLD
PROTRUSION. ALLOWABLE PROTRUSION IS 0.25
(0.010) PER SIDE. DIMENSIONS A AND B DO
INCLUDE MOLD MISMATCH AND ARE DETERMINED
AT DATUM PLANE -H-.
7. DIMENSION D DOES NOT INCLUDE DAMBAR
PROTRUSION. ALLOWABLE DAMBAR PROTRUSION
SHALL BE 0.08 (0.003) TOTAL IN EXCESS OF THE D
DIMENSION AT MAXIMUM MATERIAL CONDITION.
DAMBAR CANNOT BE LOCATED ON THE LOWER
RADIUS OR THE FOOT.
