Its core is a PLL that accepts a crystal input and produces up to 19 clock outputs, with a mix of HCSL and LVCMOS signal types. The part is specified for a maximum output frequency of 200 MHz, operating from a 3.135 V to 3.465 V supply rail. The 1:19 input-to-output ratio and differential HCSL outputs (the input is single-ended, outputs are differential) are key indicators this part is built for distributing reference clocks across multiple loads on a server motherboard, such as PCIe interfaces and CPU core logic. ## Temperature grade and environment Rated for the commercial temperature range of 0°C to 70°C, this part is intended for controlled-environment equipment such as data center server racks and enterprise computing hardware. It is not suited for industrial or outdoor deployments where extended temperature operation is required. ## Lifecycle and compliance However, the part is RoHS non-compliant, which is a critical flag for BOMs that must meet RoHS material declarations for European or other regulated markets. Designs requiring lead-free assembly will need an alternative or an exemption review. ## Sourcing and procurement reality As a current-production, active part, the CY28346ZCT is available through independent distribution channels. The RoHS non-compliance means this part is often sourced as legacy stock or for repair markets where the exemption applies; verify your BOM's regulatory requirements before committing the line.","metaTitle":"CY28346ZCT Processor-Specific Clock Generator, PLL, 200MHz","metaDescription":"Cypress CY28346ZCT processor-specific clock generator IC with PLL, 200 MHz max, 1:19 fan-out, HCSL/LVCMOS outputs.
