The document is about DS1075-IND EconOscillator/Divider. It is a fixed-frequency oscillator that requires no external components for operation. It can achieve multiple operating frequencies in the range of approximately 30kHz to 100MHz through the use of an on-chip programmable prescaler and divider.
This manual describes the DS1075-IND EconOscillator/Divider, a fixed‑frequency oscillator with user‑programmable prescalers and dividers covering roughly 30 kHz to 100 MHz. It explains the device architecture, programming flow, and how to select internal or external clock references.
Detailed sections cover pin descriptions, register maps, output enable behavior, select timing, and AC electrical characteristics, including frequency limits, jitter, and power‑up timing. The document also includes block diagrams and calculated parameter formulas for design verification.
| Maximum external clock input frequency | 50 MHz |
|---|---|
| Minimum output frequency | 29.3 kHz |
| Load capacitance | 15 pF |
| Jitter | 100 ps |
| Power‑up time | 0.1 – 1 ms |
When OE is high the oscillator runs freely; when OE is low the output is held low.
In programming mode the IN/OUT pin accepts serial data that is stored in non‑volatile memory.
The DS1075‑IND is offered in 8‑pin DIP or SOIC packages.
The device accepts an external clock up to 50 MHz.
