資料介紹
The Cypress CY25562 is a Spread Spectrum Clock Generator
(SSCG) IC used for the purpose of reducing electromagnetic
interference (EMI) found in today’s high-speed digital
electronic systems.
The CY25562 uses a Cypress-proprietary phase-locked loop
(PLL) and Spread Spectrum Clock (SSC) technology to
synthesize and frequency modulate the input frequency of the
reference clock. By frequency modulating the clock, the
measured EMI at the fundamental and harmonic frequencies
of clock (SSCLK) is greatly reduced.
This reduction in radiated energy can significantly reduce the
cost of complying with regulatory requirements and time to
market without degrading system performance.
The CY25562 is a very simple and versatile device to use. The
frequency and spread % range is selected by programming S0
and S1 digital inputs. These inputs use three (3) logic states
including High (H), Low (L), and Middle (M) logic levels to
select one of the nine available Spread % ranges. Refer
toTable 1 for programming details.
The CY25562 is intended for applications with a reference
frequency in the range of 50 to 200 MHz.
A wide range of digitally selectable spread percentages is
made possible by using tri-level (High, Low, and Middle) logic
at the S0 and S1 digital control inputs.
The output spread (frequency modulation) is symmetrically
centered on the input frequency.
Spread Spectrum Clock Control (SSCC) function enables or
disables the frequency spread and is provided for easy
comparison of system performance during EMI testing.
The CY25562 is available in an eight-pin SOIC package with
a 0-to-70°C operating temperature range.
Refer to the CY25561 for applications with lower drive requirements
and the CY25560 with lower drive and frequency
requirements.
