Description

Vectron’s V-Type Voltage Controlled Crystal Oscillator (VCXO) is a quartz stabilized square wave generator with a CMOS output and is tested at CMOS and TTL (5.0 volt operation) logic levels. The V-Type’s small footprint and low profile make it ideally suitable for PCMCIA applications as well as any other where size is limited but performance is required.

  1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
  2. Figure 1 defines these parameters. Figure 2 illustrates the equivalent five gate TTL load and operating conditions under which

these parameters are tested and specified.

  1. Symmetry is defined as (ON TIME/PERIOD with Vs= 1.4 V for TTL and Vs=2.5 V for CMOS, 5 volt operation, and Vs=1.65V

The V-Type is capable of meeting the following qualification tests. Table 3. Environmental Compliance therefore can be used for comparison purposes. Table 4. ESD Ratings used (device is backwards compatible with a lead solder assembly). The V-Type is hermetically sealed so an aqueous wash is not an issue. Table 5. Reflow Profile (IPC/JEDEC J-STD-020C)
