Cypress Introduces Programmable Clock Generator With Sub-75-Picosecond Jitter.New CY22180 Clock Delivers Very Low Cycle-to-Cycle and Period Jitter A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it always refers to some offset of time and space from the norm. For example, in a network transmission, jitter would be a bit arriving either ahead or behind a standard clock cycle for Precision Clocking in Networking Equipment and Other Applications SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- Cypress Semiconductor Cypress Semiconductor is a semiconductor design and manufacturing company. It began operations in 1982 and listed publicly in 1986. Two years later, the company shifted over to the New York Stock Exchange under the symbol, (NYSE: CY). Corp. (NYSE NYSE See: New York Stock Exchange :CY) today introduced a low-jitter, single-chip programmable clock generator. The new CY22180 clock offers a low period and cycle-to-cycle jitter output of below 75 picoseconds for its entire output frequency range, reaching as low as 60 picoseconds for the most commonly used frequencies. The low-jitter device delivers the precision clocking required by networking equipment such as routers and switches, as well as by consumer, communication and industrial applications. The CY22180 clock is available in field-programmable or factory-programmable options, providing quick sample turn and time to market, along with easy inventory management. The flexible device has a programmable output frequency with a wide range of 20 to 200 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , making it suitable for multiple applications and platforms. The CY22180 includes an integrated phase-locked loop (PLL PLL - phase-locked loop ) to generate custom frequencies from an external crystal or a driven source. "The high-precision CY22180 is the first device to provide the fast time to market of programmable clocks to designers of systems that require low jitter," said Mehdi Behnami, product marketing manager in the General Purpose Clocks Business Unit at Cypress. "It enhances our comprehensive portfolio of high performance programmable clock generators and timing distribution products." The CY22180 offers a single programmable output as well as an optional copy of the input frequency. The device has an on-chip reference oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air that is designed to run off a 10 to 30 MHz crystal, or a 10 to 133 MHz external clock signal. The CY22180 comes in a small 8-pin SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. package and requires a 3.3V power supply. The versatile clock operates in commercial and industrial temperature ranges. Price and Availability The CY22180 low-jitter clock is now in production and is priced under $1.50 each in high volume. Cypress offers in-house programming of samples and prototype quantities of the device using the CY3672-USB Programming Kit and the CY3619 Socket Adapter. Users can custom-configure the CY22180 with the web-based CyberClocks[TM] Online Software. Production quantities are available through Cypress's value-added distribution partners or by using third-party programmers from BP Microsystems and others.
