DSC1101NL3-PROGT MEMS CMOS Programmable Oscillator

Part Overview

The DSC1101NL3-PROGT is an active MEMS-based CMOS oscillator manufactured by Microchip Technology, designed for applications requiring programmable frequency generation across a wide range from 2.3 MHz to 170 MHz. This XO (Standard) oscillator operates at supply voltages between 2.25V and 3.6V and includes standby power-down functionality. The device is currently in active production status with 1,882 units available in inventory. Alternative models may be required due to inventory constraints, specific frequency stability requirements, or application-specific performance criteria.

Substitute Part Grouping Explanation

The DSC1101NL3-PROGT can be substituted with the DSC1101NL5-PROGT based on the following substitution criteria:

Both parts share identical core electrical and mechanical specifications:

• Same MEMS base resonator technology
• Identical frequency range (2.3 MHz – 170 MHz)
• Matching supply voltage range (2.25V – 3.6V)
• Same CMOS output configuration
• Identical maximum supply current (35mA)
• Same operating temperature range (-40°C – 105°C)
• Identical standby power-down function
• Same 6-VDFN surface mount package
• Matching physical dimensions and height
• Equivalent RoHS3 compliance and MSL rating

The primary difference between these parts is frequency stability specification. The DSC1101NL3-PROGT provides ±20ppm stability, while the DSC1101NL5-PROGT provides ±10ppm stability. Both parts are user-programmable blank oscillators from the same DSC1101 series.

Parameter Comparison

Engineering Selection Recommendations

Both the DSC1101NL3-PROGT and DSC1101NL5-PROGT are active production components from Microchip Technology with equivalent compliance certifications. Selection between these parts should be based on frequency stability requirements:

• Select DSC1101NL3-PROGT when ±20ppm frequency stability meets application requirements and inventory availability is sufficient.
• Select DSC1101NL5-PROGT when tighter frequency stability of ±10ppm is required, or when higher inventory availability (2,982 units) is advantageous for supply chain planning.

Both parts maintain identical electrical performance across supply voltage, frequency range, output type, and power consumption specifications. Physical package dimensions and thermal characteristics are equivalent, ensuring direct substitution at the PCB layout level. Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can DSC1101NL5-PROGT replace DSC1101NL3-PROGT in existing designs?

A: Yes. Both parts share identical electrical specifications for supply voltage, frequency range, output type, maximum current draw, operating temperature, and package dimensions. The DSC1101NL5-PROGT provides improved frequency stability (±10ppm versus ±20ppm), making it a direct functional substitute.

Q: What is the primary difference between these two oscillators?

A: The frequency stability specification differs. The DSC1101NL3-PROGT provides ±20ppm total frequency stability, while the DSC1101NL5-PROGT provides ±10ppm. All other electrical and mechanical parameters are identical.

Q: Are both parts user-programmable?

A: Yes. Both DSC1101NL3-PROGT and DSC1101NL5-PROGT are blank programmable oscillators. The user must program the desired frequency within the 2.3 MHz to 170 MHz range during manufacturing or integration.

Q: Do these parts require different PCB layouts or mounting procedures?

A: No. Both parts use the 6-VDFN surface mount package with identical dimensions (7.00mm × 5.00mm) and height (0.90mm maximum). PCB footprints and assembly procedures are interchangeable.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). Regulatory and environmental certifications are equivalent.

Q: Which part should be selected for new designs?

A: Selection depends on frequency stability requirements. For applications requiring tighter frequency tolerance, the DSC1101NL5-PROGT with ±10ppm stability is appropriate. For applications where ±20ppm stability is acceptable, either part is suitable based on availability and cost considerations.
