The DS1088C is a low-cost clock generator that pro-
duces a square-wave output without external timing com-
ponents. The fixed-frequency oscillator is available in a
factory-calibrated frequency of 133MHz. The DS1088C
has a power-down pin for power-sensitive applications.
A block diagram of the DS1088C is shown in
The internal oscillator frequency is divided by the factory-
programmed prescaler to produce an output frequency
of 133MHz.
The PDN pin disables the internal oscillator and the
oscillator output for power-sensitive applications. The
power-down pin must remain low for at least two output
frequency cycles plus 10µs for deglitching purposes. On
power-up, the output is disabled until power is stable
and the voltage-controlled oscillator has generated 512
clock cycles.

To achieve the best results when using the DS1088C,
the power supply must be decoupled with 0.01µF and
0.1µF high-quality, ceramic, surface-mount capacitors.
Surface-mount components minimize lead inductance,
which improves performance, and tend to have ade-
quate high-frequency response for decoupling applica-
tions. These capacitors should be placed as close as
possible to the V
