Raltron Electronics

<p>The Raltron COM118025-25.000-EXT-T-TR is a surface-mount crystal oscillator (XO) providing a 25.000 MHz HCMOS output. It is designed for a nominal supply voltage of 1.8 VDC with ±10% tolerance. The device delivers a clean HCMOS-compatible clock signal with a typical supply current of 6 mA and a maximum of 20 mA at 25°C.</p><p>&nbsp;</p><p>Key electrical characteristics include a frequency stability of ±25 ppm inclusive of temperature, voltage, and aging effects. The output has symmetrical duty cycle between 45% and 55% with fast rise and fall times of 3 ns maximum into a 15 pF load. An Enable/Disable function (pin 1) allows the output to be placed in high impedance state for power saving.</p><p>&nbsp;</p><p>The oscillator is housed in a standard 4-SMD, no-lead package measuring 3.2 mm x 2.5 mm x 1.0 mm with gold termination finish. It is rated for an operating temperature range of -40°C to +85°C and storage from -55°C to +125°C. The device is RoHS, REACH, and Halogen-Free compliant with MSL Level 1.</p>

<p>The COM1305-16.000-EXT-T-TR is a 16.000 MHz crystal oscillator (XO) from Raltron Electronics. It features a HCMOS output with enable/disable function and operates from a 3.3V supply voltage. The oscillator provides a frequency stability of ±50ppm over the full operating temperature range of -40°C to +85°C. The device is designed for use in a wide range of timing applications.</p><p>&nbsp;</p><p>The oscillator is housed in a compact 4-SMD, No Lead package measuring 3.20mm x 2.50mm x 1.00mm.
