Product details

PLL clock synthesizer for processor-specific timing

The Cypress CY28342OCT is a PLL-based clock synthesizer that takes a single clock input and generates up to 20 clock outputs, with a 1:20 input-to-output ratio. It operates from a 3.135 V to 3.465 V supply and delivers maximum output frequencies of 24 MHz and 48 MHz. Housed in a 48-lead SSOP package (7.50 mm width), it is intended for surface-mount assembly on motherboards, embedded processor boards, and other digital systems requiring multiple synchronized clock domains.

It is not specified for industrial or automotive environments where extended temperature or AEC-Q100 qualification would be required.

RoHS compliance note

The CY28342OCT is listed as RoHS non-compliant, meaning it contains lead (Pb) above the exemption threshold. For shipments into RoHS-regulated regions, verify whether your application qualifies for a lead-exemption category (e.g., server infrastructure, certain industrial equipment) or whether a fully RoHS-compliant alternate is needed.

Frequently asked questions

What is the input-to-output ratio of CY28342OCT?

The CY28342OCT has a 1:20 input-to-output ratio — one clock input fans out to 20 clock outputs, making it suitable for clocking multiple devices from a single source.

What is the typical application of CY28342OCT?

The CY28342OCT is a processor-specific clock generator used on motherboards, embedded processor boards, and digital systems that require multiple synchronized clock outputs at 24 MHz and 48 MHz from a single PLL source.
