Detailed Description
Applications Information
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 device has a power-down pin for power-sensitive
applications. A block diagram is shown in Figure 1.
Power-Supply Decoupling
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 adequate high-
frequency response for decoupling applications. These
capacitors should be placed as close as possible to the
Output Frequency
The internal oscillator frequency is divided by the factory-
programmed prescaler to produce an output frequency
of 312kHz to 133MHz. Contact the factory for custom
frequencies.

Chip Information
SUBSTRATE CONNECTED TO GROUND
Power-Down Mode
The PDN pin disables the internal oscillator and the oscil-
lator 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.
