| CXA3775ER [Direct Conversion IC for Digital Satellite Broadcast Tuner] |
>>Description
The CXA3775ER is an IC developed for direct orthogonal detection of L band (1 to 2GHz) IF signals in a digital
satellite broadcast reception tuner.
The CXA3775ER incorporates all the functions (RF gain control amplifier, oscillator circuit, wide-band phase
shifter circuit and other RF circuits, a baseband LPF, baseband gain control amplifier, tuning PLL) required for
a satellite broadcast tuner, and also an inductor and a varactor diode required for a tuning VCO. This makes
it possible to mount it without tuning the RF circuits.
(Applications: digital satellite broadcast tuner) |
>>Features
- Low power consumption: 430mW (Typ.) (Includes 30mW of current for controlling an external circuit)
- No need for an external inductor and a varactor diode
- 3.3V single power supply
- Reception frequency: 950MHz to 2150MHz
- High phase noise characteristic: –95 dBc/Hz 100kHz offset (Typ.)
- Internal output for controlling an external attenuator
- Crystal output for a demodulation circuit
- Small package: 36-pin VQFN
- Enables to reduce power consumption in power saving mode when not used
