Fort Myers, Fl — Fox Electronics is offering integrated SMD HCMOS TCXOs and VCTCXOs in a miniature 3.2 mm x 2.5 mm package size. The 3.3-V FOX923CH and FOX923CEH series oscillators eliminate the need for supplementary external circuitry to obtain a HCMOS output.
Ideal for timing requirements in applications such as radio frequency identification (RFID) readers, utility metering, wireless telecommunications, GPS, data transfer and test and measurement equipment, these oscillators offer significantly tighter stabilities than traditional oscillators. Stability is ±2.5 ppm over the -30 to +85 degrees Celsius operating temperature range, ±0.3 ppm over the 3.3-V (±5 percent) supply voltage and ±0.2 ppm over the 15 pF load change.
The series offers an input current (IDD) of 6 mA, an output symmetry of 40 percent to 60 percent over a frequency range of 9 MHz to 32 MHz and typical phase noise from -145 dBc/Hz at a 10 kHz offset to -85 dBc/Hz at a 10 Hz offset. Maximum reflow soldering temperature is 260 degrees celsius at 10 seconds.
These RoHS-compliant oscillators have a gold termination finish and a maximum height of 1.2 mm. The FOX923CH TCXOs (temperature-compensated crystal oscillators) feature a no-connect on Pin 1, while the FOX923CEH VCTCXOs (voltage-controlled, temperature-compensated crystal oscillators) include voltage control on Pin 1 to further tune out inaccuracies.
