This is one LOT (Qty.10) of New CYPRESS Three-PLL General-Purpose EPROM Programmable Clock Generator, Part Number: CY2081SL-667 in SO-8 Package. I have one of my customer tested this IC and concluded the 3 outputs and relationship with input at x 2.010, x 2.666, and x 6.327. See test data below.
General Spec for CY2081:
- Factory-EPROM configurable for quick availability and prototyping
- General purpose clock synthesizer for all applications – such as modems, disk drives, CD-ROM drives, Video CD players, games, set-top boxes, data/telecommunications, etc.
- Three independent configurable clock outputs
- Outputs ranging from 500 kHz to 100 MHz (5V) and up to 80 MHz for 3.3V operation
- Configurable output control pin (pin 8) can be used as an output enable, power-down, suspend or select line.
- • Phase-locked loop oscillator input derived from external crystal (10 MHz to 25 MHz) or external reference
- clock (1 MHz to 30 MHz)
- 3.3V or 5V operation (factory configured)
- 8-pin 150-mil packaging achieves minimum footprint for space-critical applications
- Sophisticated internal loop filter requires no external components or manufacturing tweaks as commonly required with external filter
I have a customer actually tested this IC (test xtal frequency from 4MHz to 16MHz) and have following test data:
