Overview
The EPSON SG-9101CG-D40PHAAC is a programmable spread spectrum crystal oscillator (XO) with CMOS output. It operates within a frequency range of 670 kHz to 20 MHz and supports a supply voltage of 1.62V to 3.63V. The device features an enable/disable function and downward spread spectrum modulation with a bandwidth of -4.00%. It is housed in a 4-SMD, no-lead package measuring 2.50mm x 2.00mm with a maximum seated height of 0.80mm.
Feature Summary
- Programmable frequency generation via manufacturer programming service
- Downward spread spectrum modulation for EMI reduction
- CMOS logic output interface
- Enable and disable control functionality
Applications
- General-purpose digital circuit clocking
- Embedded systems requiring precise timing
- Consumer electronics with EMI sensitivity
- Industrial control modules
Procurement Notes
This component requires specific frequency programming during the ordering process. Buyers must specify the desired operating frequency when placing orders through authorized distributors such as DigiKey. Verify that the supplier confirms the programmed frequency matches the design requirements before finalizing procurement. Ensure the part number suffix corresponds to the correct package and specification variant.
Selection Notes
Select this oscillator when a fixed-frequency standard XO is insufficient and programmability is required. The downward spread spectrum feature aids in meeting electromagnetic interference standards. Ensure the system voltage falls within the 1.62V to 3.63V range. The compact 4-SMD package suits space-constrained designs. Confirm the frequency step resolution meets the application's precision needs.
Part Context
The SG-9101CG series represents Epson's line of programmable spread spectrum crystal oscillators. These devices combine the stability of crystal resonators with the flexibility of programmable frequencies. The SG-9101CG-D40PHAAC specifically denotes the variant with downward spread spectrum characteristics and a 20 MHz upper frequency limit, distinguishing it from higher-frequency models in the same family.
Replacement Considerations
Direct replacements include other SG-9101CG variants with compatible packages and electrical specifications. Verify that substitute parts support the required frequency range and spread spectrum direction. Ensure the replacement maintains the same CMOS output type and supply voltage compatibility. Consult official substitution guides for cross-referencing equivalent components.
