DSC1001CE1-033.3333T

Oscillators Overview

The DSC1001CE1-033.3333T is a MEMS oscillator from Microchip Technology operating at 33.3333 MHz with LVCMOS output format. It supports a supply voltage range of 1.8 V to 3.3 V and features a frequency stability of 50 ppm. The device operates within a temperature range of -20°C to +70°C and is housed in a compact 3.2 x 2.5 mm CDFN-4 package. Maximum current consumption is rated at 10.8 mA, with a maximum duty cycle of 55%. It includes standby functionality for power management.

Oscillators Feature Summary

• Utilizes MEMS technology for robust clock generation
• Supports low voltage operation between 1.8 V and 3.3 V
• Includes standby mode for reduced power consumption
• Offers high frequency stability of 50 ppm

Oscillators Applications

• General purpose clocking for embedded systems
• Data communication interfaces requiring stable timing
• Consumer electronics with space constraints
• Industrial control applications within commercial temperature ranges

Oscillators Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the 'E1' suffix corresponds to the -20°C to +70°C industrial temperature grade rather than the extended -40°C to +85C variant found in other DSC1001 models. Ensure compatibility with 1.8V to 3.3V logic levels on the target PCB design before finalizing procurement.

Oscillators Selection Notes

Select this component when a 33.3333 MHz LVCMOS signal is required in a small footprint. The DSC1001CE1 variant is suitable for applications operating between -20°C and +70°C. Compare against the DI1 series if an extended temperature range of -40°C to +85°C is necessary. Consider the 4-VDFN package dimensions for layout constraints.

Oscillators Part Context

This part belongs to the DSC1001 family of MEMS oscillators, designed as drop-in replacements for quartz crystals. The family offers various output formats including LVCMOS and LVDS. The CE1 suffix specifically denotes the commercial temperature range and CMOS output type, distinguishing it from the DI1 (extended temp) or CI1 (extended temp tube) variants within the same frequency and package configuration.

Oscillators Replacement Considerations

Public confirmed substitute: DSC1001DI5-033.3333. Note that the DI5 variant typically supports an extended temperature range (-40°C to +85°C) compared to the CE1's commercial range (-20°C to +70°C). Verify thermal requirements before substitution.
