EFC tuning ±5ppm to ±12ppm

Customized specifications available

VEM14T - OUTLINES AND DIMENSIONS

DESCRIPTION

VEM14T series TCXOs are packaged in the industry-standard 14 pin

Dual-in-Line package. With HCMOS output, tolerances are available

from ±1.0ppm over 0° to 50°C to ±1ppm over -30° to +70°C. Supply

voltage 3.0 or 5.0 Volts. The output is controllable by EFC enabling

output variation of ±5ppm to ±12ppm.
