MAS9078
AM Receiver IC
High Sensitivity
Very Low Power Consumption
Wide Supply Voltage Range
Power Down Control
Control for AGC On
High Selectivity by Crystal Filter
Fast Startup Feature
DESCRIPTION
The MAS9078 AM-Receiver chip is a highly sensitive,
simple to use AM receiver specially intended to
receive time signals in the frequency range from 40
kHz to 100 kHz. Only a few external components are
required for time signal receiver. The circuit has
preamplifier, wide range automatic gain control,
demodulator and output comparator built in. The
output signal can be processed directly by an
additional digital circuitry to extract the data from the
received signal. The control for AGC (automatic gain
control) can be used to switch AGC on or off if
necessary. Unlike MAS1016A and MAS1016B,
MAS9078 does not require AGC control procedure in
WWVB and JJY systems.
FEATURES
Highly Sensitive AM Receiver, 0.4 µVRMS typ.
Wide Supply Voltage Range from 1.1 V to 3.6 V
Very Low Power Consumption
Power Down Control
Fast Startup
Only a Few External Components Necessary
Control for AGC On
Wide Frequency Range from 40 kHz to 100 kHz
High Selectivity by Quartz Crystal Filter
Die and TSSOP-16 Package
APPLICATIONS
Time Signal Receiver WWVB (USA), JJY (Japan),
DCF77 (Germany) and MSF (UK)
Receiver for ASK Modulated Data Signals

Notes:
1) Pin 5 between quartz crystal filter pins must be connected to VSS to eliminate DIL package leadframe
parasitic capacitances disturbing the crystal filter performance. All other NC (Not Connected) pins are also
recommended to be connected to VSS to minimize noise coupling.
2) OUT = VSS when carrier amplitude at maximum; OUT = VDD when carrier amplitude is reduced
(modulated)
- the output is a current source/sink with |IOUT| > 5 µA
- at power down the output is pulled to VSS (pull down switch)
3) AON = VSS means AGC off (hold current gain level); AON = VDD means AGC on (working)
- Internal pull-up with current < 1 µA which is switched off at power down
4) PDN = VSS means receiver on; PDN = VDD means receiver off
- Fast start-up is triggered when the receiver is after power down (PDN=VDD) controlled to power up
(PDN=VSS) i.e. at the falling edge of PDN signal.
