CY28346ZC-2

Product Overview

CY28346ZC-2 is a Cypress Semiconductor Corp application-specific clock synthesizer intended for Intel CPU server timing functions. The surface-mount device accepts a crystal input and provides one output circuit with a maximum frequency of 200MHz. It supports HCSL and LVCMOS output formats and includes a PLL. The specified supply range is 3.135V to 3.465V, and the rated operating temperature range is 0°C to 85°C ambient. The package is listed as 56-TFSOP (0.240", 6.10mm width), with supplier device package 56-TSSOP II. The part is supplied as Active.

Key Features

• Crystal input with PLL-based clock synthesis for Intel CPU server main purpose.
• One output circuit, with HCSL and LVCMOS output types and a 1:22 input-to-output ratio.
• Differential output support is specified, while the input is non-differential.
• Maximum frequency of 200MHz and supply range of 3.135V to 3.465V.
• Surface-mount 56-TFSOP package, supplier device package 56-TSSOP II, rated 0°C to 85°C ambient.

Applications

• Intel CPU server boards and platform timing subsystems that use crystal-referenced clock synthesis.
• HCSL differential clock distribution paths within server assemblies.
• LVCMOS single-ended clocking for local logic or interface blocks on the same board.

Design & Procurement Notes

Designers should confirm the board footprint against the listed 56-TFSOP package and the supplier device package 56-TSSOP II before layout release. The device provides one output circuit, so clock domains requiring additional outputs need separate planning. The specified input is crystal, and the output formats include HCSL and LVCMOS, with differential output support but non-differential input. The supply range is narrow, from 3.135V to 3.465V, and the ambient temperature range is 0°C to 85°C, which should be checked against the final operating environment. The supplied data does not verify programmable operation, so programmable behavior should not be assumed. The part is listed as Active.
