SAN JOSE, Calif. IC Works Inc. has launched a family of single-chip solutions for the Intel 440ZX AGPset for the Celeron processor. The new frequency timing generators, which are now available in volume, are targeted for basic PC plat-forms and conform to Intel's CK97 jitter specification. The devices eliminate the need for a separate frequency timing generator (FTG) and buffer by combining the two into a single device.
The single-chip solution leverages IC Works' spread-spectrum technology. "With IC Works' proprietary spread-spectrum implementation, our single-chip FTG can reduce electromagnetic interference by as much as 10 dB," said Paul Cheng, product marketing manager.
The W144 and W150 provide 16 selectable frequencies and support frequencies up to 150 MHz, while the W149 provides eight selectable frequencies and supports frequencies up to 124 MHz. All of these devices have an integrated clock buffer to support SDRAM dual in-line memory modules. Spread-spectrum and power-management features are controlled via an I2C interface.
For Intel's 440ZX AGPset and other low-cost Pentium II solutions, the W144, W149 or W150 single-chip frequency timing generator allows customers to design their systems with a low-cost FTG configuration and still benefit from EMI suppression that exceeds the specifications put forth by the Federal Communications Commission, the company said.
The W144, W149 and W150 are available now. In quantities of 10,000, the price ranges from $2.65 to $2.90 apiece.
