200 MHz spread-spectrum clock generator in 8-SOIC
The Cypress CY25100ZIF is a single-output spread-spectrum clock generator with an integrated PLL, rated for a maximum output frequency of 200 MHz. It accepts a CMOS or crystal input and delivers a CMOS output, making it a direct drop-in for reducing EMI on clock lines in digital systems. The part operates from a narrow 3.13 V to 3.45 V supply rail and is specified over the industrial temperature range of -40°C to 85°C, suiting it for telecom base stations, industrial controllers, and networking equipment where conducted emissions must be kept below regulatory limits.
Package and mounting
Housed in an 8-pin SOIC with 0.154-inch body width and 3.90 mm pitch, the CY25100ZIF is a surface-mount part that reflows on a standard lead-free profile—though the part itself is RoHS non-compliant, so verify your assembly's exemption allowance if you require full RoHS. The small footprint leaves room for decoupling capacitors close to the supply pins, which is essential for keeping PLL jitter low.
