DS1088CN-133+T

Overview

The DS1088CN-133+T is a fixed-frequency clock generator producing a 133.3MHz square-wave output without external timing components. It operates on a 2.7V to 3.6V supply and features an active-low power-down pin for energy management. The device includes factory calibration with a frequency tolerance of ±3% at +25°C, expanding to ±10% over the full voltage and temperature range (-20°C to +85°C). Active supply current reaches up to 24mA, while standby current drops to 10µA in power-down mode.

Feature Summary

• Factory-programmed 133.3MHz oscillator requiring no external crystals or resonators
• Single CMOS-compatible output with 40% to 60% duty cycle
• Active-low power-down control pin for low-power applications
• Operates within a 2.7V to 3.6V supply voltage range

Applications

• Printers
• Copiers
• Computer Peripherals
• POS Terminals
• Cable Modems

Procurement Notes

Verify the 'N' suffix indicates the TDFN-EP package type during sourcing. Confirm RoHS compliance status via the '+' designation. Check for end-of-life notifications as this component series may have discontinuation notices from Analog Devices/Maxim Integrated.

Selection Notes

Select this part when a fixed 133.3MHz clock source is required without external tuning components. Ensure the load capacitance does not exceed 50pF to maintain signal integrity. Verify that the -20°C to +85°C industrial temperature range meets the system environmental requirements.

Part Context

This component belongs to the DS1088C EconOscillator family, designed as a low-cost replacement for discrete crystal oscillators. The CN variant specifically utilizes an 8-pin Thin-Dual Flat No-Lead (TDFN) package with an exposed pad for thermal dissipation and noise reduction.

Replacement Considerations

The DS1088CX-133+T offers identical electrical performance but uses a 4-ball Wafer-Level Package (WLP) instead of the TDFN footprint.
