7N19470003 is listed in the Oscillators range at ChipApex. The manufacturer field lists TXC CORPORATION. Its product description is XTAL OSC TCXO 19.44MHZ CMOS. Review the specifications below when checking this part for your BOM.
The TXC Corporation 7N19470003 is a temperature-compensated crystal oscillator (TCXO) designed for precision timing applications. It operates at a nominal frequency of 19.44 MHz with an exceptional frequency stability of 0.14 ppm across the operating range. The device functions within a supply voltage range of 2.7V to 5.5V and supports CMOS output logic. It features an enable/disable control pin for power management. The component is housed in a compact 10-SMD, no-lead package measuring 7.00mm by 5.00mm, suitable for surface-mount assembly.
Verify the specific frequency tolerance and load requirements against your circuit design before procurement. Confirm that the 10-SMD no-lead footprint matches your PCB layout constraints. Ensure the supply voltage range aligns with your system's power rails. Check for any recent product lifecycle notifications regarding availability or obsolescence status directly from the manufacturer.
Select this component when superior frequency stability over temperature variations is critical compared to standard crystals. The integrated TCXO architecture eliminates the need for external compensation networks. Consider the enable pin feature if dynamic power saving is required during idle periods. Verify that the CMOS output swing meets the input thresholds of the downstream clock receiver.
This part belongs to the TXC TCXO series, which provides compensated oscillators for applications where standard crystals lack sufficient stability. The 7N19470003 specifically targets the 19.44 MHz band, often used in telecommunications and data conversion systems. It represents a move toward higher integration and precision in surface-mount timing solutions.
Public confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, ensure the replacement matches the 19.44 MHz frequency, 0.14 ppm stability, 10-SMD package dimensions, and CMOS output type. Verify equivalent voltage ranges and enable pin functionality.
