It accepts a crystal input and delivers up to two clock outputs at a maximum frequency of 48 MHz. The device operates from a 2.97 V to 3.63 V supply and is specified over the commercial temperature range of 0°C to 70°C. Packaged in an 8-pin SOIC, it is a surface-mount component suited for low-noise clock generation in consumer electronics, office equipment, and other indoor digital appliances where conducted or radiated EMI must be kept within regulatory limits. ## 48 MHz ceiling and 1:2 fanout — what they mean for the clock tree The 48 MHz maximum output frequency covers common microcontroller, FPGA, and memory bus clock domains up to that speed. The 1:2 input-to-output ratio means a single crystal input drives two clock outputs — enough for a small clock tree without an external fanout buffer. The PLL is enabled, so the output is synthesized from the crystal reference; the divider/multiplier is listed as No/No, indicating the PLL operates in a fixed multiplication mode rather than a programmable divider chain. For designs requiring a spread-spectrum profile to pass FCC or CISPR Class B emissions, this part modulates the output frequency to spread the peak energy. ## Lifecycle and sourcing posture The part is RoHS non-compliant, so verify the lead-free exemption or alternative if your assembly process requires RoHS compliance. ## Package and marking authenticity check The device comes in an 8-pin SOIC package with a body width of 3.90 mm (0.154-inch) and a surface-mount footprint. The supplier device package is designated 8-SOIC. For counterfeit-detection purposes, the laser-etched top marking should be clean, consistent with Cypress's font and layout for this date-code range. The 8-SOIC package is common enough that re-marked or sanded parts from other 8-pin clock generators could be swapped in. Verify the date-code lot traceability back to an authorized Cypress distributor if the supply chain is suspect.","metaTitle":"CY27020SC Spread Spectrum Clock Generator, 48 MHz, 8-SOIC","metaDescription":"Cypress CY27020SC spread-spectrum clock generator with PLL, 48 MHz max, 2.97V–3.63V supply, 0°C–70°C, 8-SOIC.
