DESCRIPTION
The VTST-Series of Single-Conversion Electronic Television tuners
provide a new, smaller size and lower cost interface for NTSC and
PAL applications. These tuners provide a common package size,
which is the smallest in the industry.
These units provide a common mechanical foot print and electri-
cal interface through all models. The pin position and pitch, and
assigned functions are always in the same position, so now you can
change tuners without changing the PCB.

The tuners are available in Voltage Synthesizer models, which
provide a Voltage Controlled Oscillator input and Band Switch con-
trols. Tuner models are also available with internal Phase-Locked
