Overview
The SG-9101CG-D40PGCAC is a programmable spread spectrum crystal oscillator (XO) manufactured by EPSON. It features a CMOS output and operates within a supply voltage range of 1.62V to 3.63V. The device supports frequency programming from 670 kHz to 20 MHz with a downward spread bandwidth of -4.00%. It includes an enable/disable function and functions in a standby mode with a maximum disabled current of 3.7 mA. The component is housed in a 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 0.80mm. It is rated for operation between -40°C and +85°C.
Feature Summary
- Programmable frequency generation within the 670 kHz to 20 MHz range
- Integrated downward spread spectrum modulation capability
- Low power consumption with dedicated enable and disable control pins
Applications
- High-speed serial communication interfaces requiring jitter reduction
- Data acquisition systems needing precise clock synchronization
- Embedded computing platforms utilizing spread spectrum techniques for EMI compliance
Procurement Notes
Verify that the specific order notes explicitly state the required target frequency, as this model requires programming upon request. Confirm the supply voltage requirements align with the 1.62V to 3.63V operational range. Ensure the design accommodates the 4-SMD no-lead package dimensions and thermal characteristics for the specified operating temperature range.
Selection Notes
Select this component when system design mandates active spread spectrum modulation to mitigate electromagnetic interference. The choice is appropriate for applications requiring flexible frequency tuning across a wide low-frequency band. Consider the enable/disable functionality for power management strategies in battery-operated or energy-efficient devices.
Part Context
This part belongs to the SG-9101 series of programmable spread spectrum crystal oscillators. It shares the same physical footprint and electrical interface standards as other variants in the family, differing primarily in factory-programmed frequency specifications and specific spread spectrum parameters defined during the ordering process.
Replacement Considerations
Direct substitutes include SG-9101CG-D40SGCAC and SG-9101CB-D40PGCAC. These alternatives offer similar form factors and electrical characteristics but may differ in specific frequency ranges or manufacturing batches. Verify pin compatibility and software configuration requirements before substitution.
