Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Recommended Operating Conditions
(VCC = 2.7V to 3.6V, TA = -20°C to +85°C, unless otherwise noted.)
(VCC = 2.7V to 3.6V, TA = -20°C to +85°C, unless otherwise noted.)
Note 1: All voltages are referenced to ground.
Note 2: Typical frequency shift due to aging is within ±0.2%. Aging stressing includes level 1 moisture reflow preconditioning (24hr
+125°C bake, 168hr +85°C/85%RH moisture soak, and three solder reflow passes +240°C +0°C/-5°C peak) followed
by1000hr (max) VCC biased +125°C OP/L, 1000hr unbiased +150°C bake, 1000 temperature cycles at -55°C to +125°C,
and 168hr +121°C/2 ATM steam/unbiased autoclave.
Note 3: This is the change in output frequency due to changes in voltage at TA = +25°C.
Note 4: Guaranteed by design.
Note 5: This is the change in output frequency due to changes in temperature from the +25°C frequency at VCC = 3.3V.
Note 6: This indicates the time elapsed between power-up and the output becoming active. An on-chip delay is intentionally intro-
duced to allow the oscillator to stabilize. tSTAB is equivalent to approximately 512 clock cycles and will depend on the pro-
grammed oscillator frequency.
Note 7: Output disabled in two cycles or less of the output frequency.
Note 8: Output voltage swings may be impaired at high frequencies combined with high-output loading.

Pin Description
Pin Coniguration
Detailed Description
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.
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.
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.
Applications Information
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
VCC and GND pins.
