Tailor-made crystal oscillator from 1.0 MHz to 125 MHz. On your order, please specify your specs!!Designed by microwavemont in Japan
Notice Apr.24: Due to the current international shipping delay, now only the domestic order is accepted. I will recover it ASAP shipping status recover.
What is it? Pre-programmed crystal oscillator. The frequency range is from 1.0 MHz to 125 MHz with 5 to 6-digit accuracy. The detail specs are available [at SG-8002DC datasheet].(https://support.ep...Read More…

Sometimes we need "special frequency clock" but if it is not "commercial standard", it is very hard to obtain. The SG-8002DC by SEIKO EPSON is a programmable crystal modules in which the output is generated by internal PLL synthesizer. This time I obtained the programmer for this module and I am very happy if I can be some help of your "special project" by this signal generator. The module used in this item is SG-8002DC, which has 8-pin DIP size. The price of this item is one oscillator component.
Output frequency of your need. We can specify from 1.0000 MHz to 125.000 MHz. More than 6-digit can be specified but it will be truncated.
Operation voltage. Selectable voltage is 3.3 V or 5.0 V
Pin #1 operation. The pin can be set up as "OE, output enable" or "~ST, STOP". The "OE" will continue oscillating during output disable but "~ST" will stop its oscillation when "~ST" activated. "~ST" will lead low power operation for standby but will take some time for stabilization for restarting. Please refer the datasheet
Frequency tolerance (B, C, or M). Please refer the datasheet for the exact information for "B, C, M" class.
Example of ordering information
"31.416 MHz", "5.0 V", "OE", "B"
(frequency, voltage, #1 pin function, tolerance class)
Please write above information for "Additional Instructions" Some frequency range or operation voltage, frequency tolerance "M" or "B, C" are not selectable. Please [refer the datasheet].(https://support.epson.biz/td/api/doc_check.php?dl=brief_SG-8002CA&lang=en)
One important notice before your order
The frequency accuracy and stability is excellent as in the datasheet but do not expect ultra high accuracy as rubidium oscillator. In addition, the output of this oscillator is generated by internal PLL circuit and it has "jitter". Please read "jitter specification" in the datasheet.
This oscillator one-time programmable device. Once its frequency and program is written in the device, they cannot be re-written nor changed.
Each of order, its spectrum and phase noise measurement result (printed) will be attached as the image above.
