266 MHz output — what it means for the bus
The maximum output frequency is 266 MHz. The differential outputs on the output side allow high-speed clock routing with reduced noise coupling.
Package and footprint
Housed in a 48-lead BSSOP (0.295-inch body width, 7.50 mm), the CY28405OC-2T is a surface-mount part that sits on a standard SSOP-48 footprint. The supplier device package is listed as 48-SSOP, so the land pattern is the same as any other 48-pin SSOP clock or logic IC. No special thermal pad or heatsink is required at this power level.
Lifecycle and compliance
One important catch: it is RoHS non-compliant. For BOMs that must meet EU RoHS or similar green directives, this part will not pass without an exemption. For non-RoHS designs — legacy telecom, military, or exempt industrial equipment — it is a straightforward drop-in.
Sourcing and availability
Because the lifecycle is Active, there is no urgency from an end-of-life standpoint, but the RoHS restriction may limit the number of stocking distributors who carry it — so lead time can vary. Submit an RFQ for a firm delivery window.
