VCXO 16.384 MHz to 130 MHz Miniature Surface Mount Voltage-Controlled Crystal Oscillator 5mm x 7mm DESCRIPTION Statek’s 5 mm x 7 mm surface mount Voltage-Controlled Crystal Oscillator is designed for applications requiring a highlypullable 3.3 V CMOS-output VCXO with a small footprint. Offered at frequencies from 16.384 MHz to 130 MHz with operation over wide temperature ranges (up to -40°C to +105°C), these VCXOs offer exceptional performance in a small package. Low Profile DIMENSIONS FEATURES High Absolute Pull Range (APR) Low phase noise - Low phase jitter Wide frequency range Non-standard frequencies supported Extended Industrial temperature range -55ºC option available APPLICATIONS A B C (SM1) C (SM3/SM5) D E Military & Aerospace Avionics Communications Projectiles TERMINATIONS Designation SM1 SM3 SM5 PACKAGE DIMENSIONS Dimension Termination Gold Plated (Pb Free) Solder Dipped Solder Dipped (Pb Free) Minimum mm 6.86 4.85 1.55 1.65 1.19 1.07 Typical mm 7.00 5.00 1.75 1.85 1.40 1.27 Maximum mm 7.16 5.16 1.95 2.05 1.41 1.47 SUGGESTED LAND PATTERN inches (mm) 0.100 (2.54) 0.077 (1.96) ENABLE/DISABLE OPTIONS (T/N) Statek offers two enable/disable options: T and N. The T-version has a Tri-State output and continues to oscillate internally when the output is put into the high Z state. As a result, when re-enabled, the oscillator does not have to restart and an output with a stable frequency resumes almost immediately. The N-version does not have PIN 2 connected internally and so has no enable/disable capability. The following table describes the Enable/Disable option T. 0.144 (3.65) 0.070 (1.80) 0.200 (5.08) PIN CONNECTIONS ENABLE/DISABLE OPTION T FUNCTION TABLE Enable (PIN 2 High*) Disable (PIN 2 Low) Output Frequency Output High Z State Oscillator Oscillates Oscillates Current Normal Lower than normal * When PIN 2 is allowed to float, it is held high by an internal pull-up resistor. 1. 2. 3. 4. 5. 6.
