Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Ensure that the 1.8V supply voltage aligns with your target platform's power rails. Confirm that the LVCMOS output swing is compatible with the receiving logic inputs. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Oscillators Selection Notes

Select this oscillator when a 37.03 MHz reference frequency is required for LVCMOS-compatible circuits. Consider the 1.8V supply constraint and the availability of a power-down pin for energy-sensitive designs. Evaluate the 2.0x1.6 mm footprint against available PCB space. Compare performance against other Mercury QHTF series variants if different frequencies or voltage levels are needed.

Oscillators Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers standard XO configurations with various frequency options and supply voltages. The '18' prefix indicates the 1.8V supply variant, while 'PD' denotes the power-down feature. These components are commonly used in consumer electronics and industrial equipment requiring stable clock sources.

Oscillators Replacement Considerations

Direct replacements must match the 37.03 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter. Consult manufacturer cross-reference lists for equivalent parts from other suppliers.
