Transceivers Target Serial Apps

Supporting data rates of 50 to 200 Mbps (5 to 20 MB/s), the products represent the latest additions to the HOTLink family of integrated, point-to-point, serial transceivers. The CY7C924DX offers additional logic to increase ease-of-use and system performance. The CY7C954DX is a UTOPIA extender for ATM applications that uses similar functional blocks to the 924DX but adds an interface compliant with the UTOPIA Level I and II standards to increase design flexibility and reduce time-to-market. The previously announced CY7C9689DX is a low-power transceiver compatible with AMD's discontinued TAXIchip chipset. The devices include 256 bytes of FIFO on the transmit and receiver channels and are compatible with standard media, such as fiber optics, twisted-pair wire, and coaxial cable. The 924DX and 954DX transceivers support 8B/10B encoding standards. The 9689DX supports 4B/5B and 5B/6B TAXIchip and Fiber Distributed Data Interface (FDDI) standards. The chips use an integrated PLL clock synchronizer that eliminates the need for external capacitors and resistors, along with a built-in self-test to perform loop-back and link integrity diagnostics. The 954DX UTOPIA level I- and II-compliant devices support Header Error Correction (HEC) and multi-PHY addressing.
