SG-9101CA-C02SGABB

Overview

The SG-9101CA-C02SGABB is a programmable XO CMOS oscillator from EPSON, operating within a frequency range of 670 kHz to 170 MHz. It supports a supply voltage of 1.62V to 3.63V and features a standby function. The device utilizes a 4-SMD, no-lead package with dimensions of 7.00mm x 5.00mm and a maximum height of 1.30mm. It offers an EMI reduction capability through downward spread spectrum modulation with a bandwidth of -0.50%. The component operates across a temperature range of -40°C to 85°C and includes a disable current specification of 3.7 mA maximum.

Feature Summary

• Integrates spread spectrum technology to dynamically modulate clock frequency for electromagnetic interference suppression.
• Supports custom frequency programming via the SG-Writer II tool to optimize circuit design requirements.
• Provides low power consumption with a dedicated standby mode for energy efficiency.

Applications

• Automotive electronic systems requiring high electromagnetic compatibility.
• Communication equipment needing precise clock signals with reduced noise.
• Computer peripherals and general-purpose digital circuits.

Procurement Notes

Verify the specific order suffix against the manufacturer datasheet to confirm the exact spread spectrum configuration and pinout. Ensure that the required frequency falls within the 670 kHz to 170 MHz operational range. Confirm that the 7050 package dimensions align with the PCB layout constraints. Check for any specific programming requirements or tools needed before finalizing the procurement process.

Selection Notes

Select this model when designing systems that require flexible frequency generation alongside strict EMI management standards. The downward spread spectrum feature makes it suitable for applications where reducing peak spectral emissions is critical. Consider the 7050 footprint if space allows for larger components compared to smaller series options. Evaluate the standby current specifications against overall system power budgets.

Part Context

This component belongs to the SG-9101 series of programmable spread spectrum crystal oscillators. The CA variant specifically denotes the 7050 package size, distinguishing it from other form factors like 2520 or 3225 within the same product line. The series is designed to replace fixed-frequency oscillators in designs demanding lower electromagnetic interference.

Replacement Considerations

Direct substitutes include other SG-9101CA variants with different spread spectrum settings, such as SG-9101CA-C07SGABB for center spread spectrum. Cross-series replacements may involve SG-9101CB or SG-9101CG models if package size adjustments are permissible.
