Reference
10)Limits are related to the tank circuit used in the application board (see Chapter 3 on page 27). Frequency bands
may be adjusted by the choice of external components.
11)The frequency shift is defined as a change in oscillator frequency when the supply voltage varies from
V
= 5 to 4.75 V (4.5 V) or from V
CC
= 5 to 5.25 V (5.5 V). The oscillator is free running during this
measurement.
12)The frequency drift is defined as a change in oscillator frequency if the ambient temperature varies from T
A
=
25 to 50 °C or from T
A
= 25 to 0 °C. The oscillator is free running during this measurement.
13)The switch-on drift is defined as a change in oscillator frequency between 5 s and 15 min after switch-on. The
oscillator is free running during this measurement.
14)see Figure 8 Application Circuit for DVB-T on page 28.
15)see Figure 7 Application Circuit for ATSC on page 27.
16)The supply ripple susceptibility is measured in the application board (see Chapter 3 on page 27), using a
spectrum analyser connected to the IF output. An unmodulated RF signal is applied to the test board RF input.
A sinewave signal with a frequency of 500 kHz is superposed onto the supply voltage (see 4.5.8 on page 58).
The amplitude of this ripple is adjusted to bring the 500 kHz sidebands around the IF carrier to a level of 53.5
dBc referred to the carrier.
17)This is the level of divider interferences close to the IF frequency. For example channel S3: f
= 158.15 MHz,
1/4 f
OSC
= 39.5375 MHz. Divider interference is measured with the application board (see Chapter 3 on page
27).
(i.e. not connected to any load or cable). The MIDIN and HIGHIN inputs are connected to a hybrid. The
measured level of divider interference are influenced by layout, grounding and port decoupling. The
measurement results between various applications and the reference board could vary as much as 10 dB.
18)Crystal oscillator interference means the 4 MHz sidebands caused by the crystal oscillator. The rejection has
to be greater than 60 dB for an IF output of 100 dBμV.
19)The reference frequency rejection is the level of reference frequency sidebands (e.g. 62.5 kHz) related to the
carrier. The rejection has to be greater than 60 dB for an IF output of 100 dBμV.
