• Description: Phase-Aligned Clock Multiplier
• Manufacturer: CYPRESS [Cypress Semiconductor]

Pin Definitions
Functional Description
The CY2300 is a 4-output 3.3V phase-aligned system clock
designed to distribute high-speed clocks in PC, workstation,
datacom, telecom, and other high-performance applications.
The part allows the user to obtain 1/2x, 1x, 1x and 2x REFIN
output frequencies on respective output pins.
The part has an on-chip PLL which locks to an input clock
presented on the REFIN pin. The input-to-output skew is guar-
anteed to be less than ±200 ps, and output-to-output skew is
guaranteed to be less than 200 ps.
Multiple CY2300 devices can accept the same input clock and
distribute it in a system. In this case, the skew between the
outputs of two devices is guaranteed to be less than 400 ps.
