FAQ

What is the nominal frequency and mode of operation for VXM7-1363-57M1425000?

The VXM7-1363-57M1425000 operates at a nominal frequency of 57.1425 MHz in fundamental AT-cut mode. It is not an overtone device and requires no external filtering. This frequency is commonly used for Ethernet PHY reference clocks and FPGA transceiver reference inputs. The VXM7-1363-57M1425000 achieves this using a precisely laser-trimmed quartz blank with controlled mass loading.

Does VXM7-1363-57M1425000 require load capacitors, and what value is specified?

Yes, the VXM7-1363-57M1425000 is a parallel-resonant crystal requiring external load capacitors. Its specified load capacitance is 12 pF, meaning the total effective capacitance seen by the crystal-including PCB trace capacitance, oscillator IC input capacitance, and discrete capacitors-must sum to 12 pF. The VXM7-1363-57M1425000 datasheet confirms this value in Table 1 under "Load Capacitance, ordering option".

What is the maximum allowable drive level for VXM7-1363-57M1425000?

The VXM7-1363-57M1425000 has a maximum drive level of 100 µW, as stated in Table 1 of its datasheet. Exceeding this may cause activity dips, frequency shifts, or accelerated aging. Oscillator circuits must be designed to limit crystal current accordingly-typically achieved via feedback resistor adjustment. The VXM7-1363-57M1425000's low 60 Ω ESR helps maintain safe drive levels even with moderate loop gain.

Is VXM7-1363-57M1425000 compatible with lead-free reflow processes?

Yes, the VXM7-1363-57M1425000 is fully compatible with Pb-free reflow. Its gold-over-nickel terminations and ceramic package meet J-STD-020 MSL 1 classification, supporting peak temperatures up to 260 °C for ≤30 seconds. The VXM7-1363-57M1425000 reflow profile is documented in Table 4, specifying time above 217 °C (60–150 sec) and ramp rates compliant with IPC-A-610.

What environmental qualifications does VXM7-1363-57M1425000 meet?

The VXM7-1363-57M1425000 meets MIL-STD-883 requirements for mechanical shock (Method 2002, Condition B), vibration (Method 2007, Condition A), temperature cycling (Method 1010, Condition B), and gross/fine leak (Method 1014). It also passes solderability testing per MIL-STD-202-210. These qualifications are confirmed in Table 3 of the official datasheet and apply directly to the VXM7-1363-57M1425000 variant.
