7XL-42.000MDD-T is listed in the Oscillators range at ChipApex. The manufacturer field lists TXC CORPORATION. Its product description is XTAL OSC XO 42.00MHZ 1.8V CMOS. Review the specifications below when checking this part for your BOM.
The 7XL-42.000MDD-T is a standard clock oscillator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a frequency of 42 MHz with CMOS output logic. The device supports a supply voltage of 1.8 V and features an enable/disable control function. Frequency stability is specified at +/-25 ppm over the operating temperature range of -40°C to +85°C. The component utilizes a ceramic package with dimensions of 3.2 mm x 2.5 mm.
Verify the specific ordering suffix to ensure the correct voltage level and stability grade are selected. Confirm that the 1.8V supply requirement aligns with the target system design. Check for RoHS compliance status if environmental regulations apply. Ensure the SMD footprint matches the PCB layout specifications before finalizing procurement orders.
Select this component when a 42 MHz reference signal is required with tight stability constraints. Consider the 1.8V operating voltage as a primary constraint for low-power designs. Evaluate the enable/disable feature against system power cycling requirements. Compare the 3.2x2.5mm package size against available board space limitations.
This part belongs to the TXC 7XL series of quartz oscillators, which are characterized by tight frequency stability and wide temperature operation capabilities. The series is engineered for demanding electronic applications requiring reliable timing sources in compact surface-mount packages.
