TYPICAL APPLICATION
U
Voltage-Controlled Crystal Oscillator (VCXO)
Figure 20, a variant of the basic crystal oscillator, permits
voltage tuning the output frequency. Such voltage-con-
trolled crystal oscillators (VCXO) are often employed
where slight variation of a stable carrier is required. This
example is specifically intended to provide a 4
× NTSC
sub-carrier tunable oscillator suitable for phase locking.
The LT1394 is set up as a crystal oscillator, operating
similarly to Figure 3 (a). The varactor diode is biased from
the tuning input. The tuning network is arranged so a 0V
to 5V drive provides a reasonably symmetric, broad tuning
range around the 14.31818MHz center frequency. The
indicated selected capacitor sets tuning bandwidth. It
should be picked to complement loop response in phase
locking applications. Figure 21 is a plot of tuning input
voltage versus frequency deviation. Tuning deviation from
the 4
× NTSC 14.31818MHz center frequency exceeds
±240ppm for a 0V to 5V input.
