SGR-8002DC-PTB

Overview

The EPSON SGR-8002DC-PTB is a programmable crystal oscillator (XO) from the SG-8002 series, manufactured by EPSON. It utilizes a standard crystal resonator and delivers TTL output signals within a frequency range of 1 MHz to 125 MHz. The device operates on a 5V supply voltage with a maximum current consumption of 45mA during operation and 30mA in disabled mode. Frequency stability is specified at ±50ppm across an operating temperature range of -20°C to 70°C. It features enable/disable functionality and is housed in an 8-DIP package with 4 leads (half-size), measuring 13.70mm x 6.60mm x 5.30mm.
