CXA3068N
L-band Down Converter for Satellite Tuner
Description
16 pin SSOP (Plastic)
The CXA3068N is a monolithic IC to down-convert
the L-band (930 to 2150 MHz) signal for the satellite
broadcasting receiver. It has a double-balanced
mixer, local oscillator circuit and IF amplifier on chip.
Features
• Balance-type Colpitts oscillator circuit provides a
stable and wide range oscillation.
Oscillation frequency : 2.63 GHz
Absolute Maximum Ratings (Ta=25 °C)
• Small leak of the local oscillation signal due to the
double-balanced mixer.
• Supply voltage
VCC –0.3 to +5.5
V
• Storage temperature
• Allowable power dissipation
Tstg –55 to +150 °C
• Oscillation frequency drift is small, caused by the
change of impedance at the pre-stage of RF input.
• Local oscillator output circuit for PLL.
• Single 5 V power supply operation.
PD

mW
(When mounted on board)
• Low current consumption.
ICC=53 mA (typ.)
Operating Conditions
• Supply voltage
• 16-pin SSOP package contributes to reduction in
VCC 4.75 to 5.3
