DBL1019

The DBL1019 is designed as a AM electronic tuner IC with high performance. It is greatly inproved cross modulation characteristics. Typical applications is the AM car radios and the home receivers.

DBL1019 has seven features. (1)Low noise. (2)Vcc variation compensation. (3)The local OSC buffer output facilitates designing of electronic tuner system, frequency display and etc. (4)The narrow band signal meter output is usable as auto search stop signal. (5)The excellent cross modulation characteristics prevent not only adjacent-channel interference but also interference caused by all channels.with in broadcast band. (6)Double balanced different MIX. Those are all the main features.

Some absolute maximum ratings of DBL1019 have been concluded into several points as follow. (1)Its supply voltage would be 16V. (2)Its supply current would be 41mA. (3)Its MIX output and IF amp output voltage would be 24V. (4)Its MIX input and RF amp 1 input voltage would be 5.6V. (5)Its local OSC current would be 2mA. (6)Its power dissipation would be 730mW. (7)Its operating temperature range would be from -20°C to 70°C. (8)Its storage temperature range would be from -40°C to 125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of DBL1019 are concluded as follow. (1)Its quiescent current would be min 13.5mA and typ 22.5mA and max 32.5mA. (2)Its supply current would be min 20mA and typ 30mA and max 41mA. (3)Its detector output would be min -29dBm and typ -25dBm and max -21dBm for Vod1 16dBu input 30% mod and would be min -15dBm and typ -12dBm and max -9dBm for Vod2 74dBu input 30% mod. (4)Its signal to noise ratio would be min 51dB and typ 56dB. (5)Its input voltage at signal meter output 1V would be min 18dBu and typ 24dBu and max 30dBu. And so on.
