The DS1088L is a low-cost clock generator that pro-
duces a square-wave output without external timing
components. The fixed-frequency oscillator is available
in factory-calibrated frequencies from 312kHz to
133MHz. The DS1088L has a power-down pin for
power-sensitive applications. A block diagram of the
DS1088L is shown in
The internal oscillator frequency is divided by the facto-
ry-programmed prescaler to produce an output fre-
quency of 312kHz to 133MHz. See the Standard
Frequency Options

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 sta-
ble and the voltage-controlled oscillator has generated
512 clock cycles.
To achieve the best results when using the DS1088L,
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 to
