1.3 GHz universal bus-controlled
TV synthesizer
TSA5520; TSA5521
APPLICATION INFORMATION
Tuning amplifier
The tuning amplifier is capable of driving the varicap
voltage without an external transistor. The tuning voltage
output must be connected to an external load of 27 k
which is connected to the tuning voltage supply rail.
Figures 11 and 12 show a possible loop filter.
The component values depend on the oscillator
characteristics and the selected reference frequency.
Crystal oscillator
The crystal oscillator uses a 4 MHz crystal connected in
series with an 18 pF capacitor thereby operating in the
series resonance mode. Connecting the oscillator to the
supply voltage is preferred but it can, however, also be
connected to ground.

C-bus sequences (SW = LOW)
Tables 8 to 12 show the various sequences where f
osc
= 100 MHz, BS4 = ON, I
CP
= 280
μ
A, N = 512, f
xtal
= 4 MHz,
S = START, A = acknowledge and P = STOP. The sequence is as follows:
START + address byte + divider byte 1 + divider byte 2 + control byte + band switch byte + STOP.
For the complete sequence see Table 8 (sequence 1) or Table 9 (sequence 2).

C-bus sequences are not allowed. Other I

C-bus addresses may be selected by applying an appropriate voltage
to the CE input.
Examples of 3-wire bus sequences (TSA5520; SW = OPEN)

18-bit sequence (f
osc
= 800 MHz, BS4 = ON)
Table 14
19-bit sequence (f
osc
= 650 MHz, BS3 = ON)
The reference divider is automatically set to 512 unless RSB has been programmed to 0 during a 27-bit sequence.
