Overview
The Semtech GO1555-IXTE3 is a Voltage Controlled Oscillator (VCO) designed for high-frequency applications. It operates within a frequency range of 1483.5 MHz to 1485 MHz, centered at 1484.25 MHz. The device requires a tuning voltage range of 1 VDC to 1.5 VDC and exhibits a pushing factor of 1.5 MHz/V. Electrical specifications include a maximum power consumption of 20 mW and a current rating of 8 mA. It functions on a 2.5 V supply and supports an operating temperature range from -40°C to 85°C. The component is housed in an 8-SMD, No Lead package with dimensions of 4.50mm x 3.20mm.
Feature Summary
- Compact surface-mount design suitable for space-constrained layouts
- Integrated voltage control for precise frequency adjustment
- Low power consumption profile optimized for efficiency
Applications
- Optical communication systems
- Fiber optic transceivers
- Telecommunications infrastructure
Procurement Notes
Verify the EOL status and discontinuance notification prior to procurement. Confirm that the 8-SMD package dimensions align with PCB footprint requirements. Ensure the tuning voltage range of 1 VDC to 1.5 VDC matches the system's control circuitry capabilities. Validate the operating temperature range against environmental conditions.
Selection Notes
Select this VCO when a stable 1484.25 MHz signal is required for optical networking applications. Consider the low pushing factor for frequency stability under varying control voltages. Evaluate the 8 mA current draw against available power budgets. The compact 4.50mm x 3.20mm package facilitates integration into dense circuit boards.
Part Context
This component belongs to Semtech’s portfolio of frequency control elements, specifically Voltage Controlled Oscillators. It complements their broader suite of optical interconnect solutions, including transimpedance amplifiers and drivers. The GO1555 series targets high-speed data transmission markets requiring precise clock generation or modulation signals.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material. Due to the End-of-Life (EOL) status, alternative sourcing should be evaluated carefully. Verify compatibility with existing board designs if considering cross-referencing other VCO models.
