1 / 10 page  DA9078.003 28 January 2004 1 (10) 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 APPLICATIONS • 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 • Time Signal Receiver WWVB (USA), JJY (Japan), DCF77 (Germany) and MSF (UK) • Receiver for ASK Modulated Data Signals BLOCK DIAGRAM AGC Amplifier Demodulator & Comparator Power Supply/Biasing RFI OUT QI QO PDN VDD VSS AGC DEC AON (=AGC on) |
