Compact and compact programmable crystal oscillator

SPXO quickly delivers crystal oscillators that include PLL circuits and can be modulated to output the desired frequency. It can be modulated to any output frequency, which is beneficial for short-term delivery and small batch production. The principle is to use a special programming tool to write frequency data into a blank crystal oscillator. Epson offers programmable crystal oscillators SG-8018 and SG-8101 series, which are programmed using the SG WriterII programming tool. Programmable oscillators can shorten delivery time to a few days and are commonly used in high-end smart products.

Epson's programmable crystal oscillators: SG-8018 and SG-8101 series. The SG-8018 and SG-8101 use Epson IC patented technology for efficient and time-saving delivery; The second is compact and small, compatible with a minimum package size of 2.5 * 2.0mm. The third high precision includes a 10-year aging rate (± 50ppm) for frequency accuracy; The fourth delivery period is short, with a 24-hour sampling and delivery time, and a 2-week delivery time from order to factory; Fifth Wide Temperature Range: Programmable crystal oscillators have a wider operating temperature range, increasing from 85 ℃ to 105 ℃

The frequency range of this series of programmable crystal oscillators is 0.67 MHz to 170 MHz (1 ppm per step), with a wide frequency range; The power supply voltage ranges from 1.62V to 3.63V, with the function of enabling (OE) or standby (ST (--)). The frequency stability is 50ppm (-40 ° C to+105 ° C), including frequency aging (+25 ° C, 10 years). In terms of assembly, in order to achieve optimal vibration characteristics, a 0.1 μ F capacitor should be placed between VCC and GND. In addition, it is recommended that the capacitor be placed on the device side of the PCB, such as near the device, and connected together through short wiring as much as possible. In terms of product material safety, it complies with the EU RoHS certification and is a lead containing product exempt from EU RoHS certification inspection. In addition, the SG-8018 and SG-8101 series are divided into four different packaging specifications to meet customers' size requirements. The external size specifications are shown below:

• CA：  7.0 x 5.0x 1.3mm

• CB：  5.0 x 3.2 x 1.1mm

• CE：  3.2 x 2.5  x 1.05mm
