U2750B-B  
Tuner IC for DAB  
Description  
The U2750B-B is a monolithically integrated tuner  
circuit  
fabricated  
with  
Atmel  
Wireless  
&
Electrostatic sensitive device.  
Microcontrollers’ advan-ced UHF5S technology.  
Designed for applications in DAB receivers, it includes  
two selectable mixers, one VCO, a SAW-filter driver, an  
LO output buffer, a tristate band switch and an AGC-volt-  
age generation block.  
Observe precautions for handling.  
FD e8a.5tuVrseuspply voltage  
D Balanced LO output for PLL  
D RF frequency range 70 MHz to 260 MHz  
D SAW-filter driver with low impedance output  
D Two identical mixers, selectable by band-switch input  
D Power measurement and generation of AGC voltage  
by charge-pump output  
D Balanced mixer input, balanced mixer output  
(open collector)  
D Three charge-pump currents selectable  
(zero, low, high)  
D High-impedance mixer inputs  
D Four-pin voltage-controlled oscillator  
D Voltage regulator for stable operating characteristics
