DS1088LU-737/T+W

P1-P3P4-P6P7-P8
General 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.

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.

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

and 168hr +121°C/2 ATM steam/unbiased autoclave.
Note 3: This is the change in output frequency due to changes in voltage at T
A
= +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 V
CC
= 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. t
STAB
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.
