Table 6. Tuner Performance (Low Power Settings)
settings for the reference design shown in Figure 30, which
includes the applicable filtering. Note that this tuner can be
operated in an extended frequency band of 861 MHz to
1000 MHz. In this extended band, Gain Variation and Noise
Figure specs increase 1.0 dB.
Supply Current — Low power mode
Supply Current — All blocks shutdown
Noise Figure Channel 57 MHz
Noise Figure Channel 861 MHz
Noise Figure Channel 1000 MHz
Conversion Gain — All max settings
Conversion Gain — All min settings
Gain Variation — Variation in Gain for one tuner over 57MHz-861MHz
IF Gain Flatness — within any channel
RF AGC Range
IF AGC Range 0.5 V to 3.3 V
