Functional Description
The CY2303 is a 3 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 user to obtain 1x, 2x, and 4x Ref output
frequencies on respective output pins.
The CY2303 has an on-chip PLL, which locks to an input clock
presented on the REFIN pin. The PLL feedback is internally
connected to the REF output. The input-to-output skew is
guaranteed to be less than ±200 ps, and output-to-output skew
is guaranteed to be less than 200 ps.
Multiple CY2303 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.
The CY2303 is available in commercial and industrial temper-
ature ranges.
