That 1:27 ratio means one crystal feeds an entire board's clock tree without cascading multiple PLLs — a common pain point when different peripherals need different reference clocks and the MCU's internal PLL doesn't have enough outputs. The outputs are differential-capable, which helps maintain signal integrity over longer PCB traces or when driving differential receivers directly. ## Three output frequencies — why those numbers matter The three output frequencies — 14.318 MHz, 24 MHz, and 48 MHz — are not arbitrary. 14.318 MHz is the legacy PC/AT colour-burst crystal frequency (3.58 MHz × 4), still used in some video and legacy-interface designs. 24 MHz is a common base frequency for USB, audio codecs, and many MCU PLL reference inputs. 48 MHz is the standard USB full-speed/high-speed reference. Having all three on one chip means a single crystal (typically 14.318 MHz) generates the other two via the internal PLL, saving board space and BOM cost. The 48 MHz output also doubles as a clean clock for a secondary processor or PHY. ## Package and temperature — where it lives on the board Housed in a 56-BSSOP (0.295\", 7.50 mm width) — also referred to as 56-SSOP — this is a surface-mount part with a standard 0.65 mm pitch. Not rated for industrial or automotive use. ## Lifecycle and sourcing It remains a viable design-in choice for new BOMs. RoHS non-compliant, so it is not suitable for lead-free assembly lines unless you have a waiver or a separate RoHS-compliant variant.","metaTitle":"CY2220PVC-1 Clock Synthesizer, 1:27 Fanout, 48 MHz Max","metaDescription":"Cypress CY2220PVC-1 clock synthesizer/driver.
