CY7B923 CY7B933 HOTLink™ Transmitter/Receiver Features Fibre Channel compliant IBM ESCON® compliant DVB-ASI compliant ATM compliant 8B/10B-coded or 10-bit unencoded Standard HOTLink: 160–330 Mbps High Speed HOTLink: 160–400 Mbps for high speed applications Low Speed HOTLink: 150–160 Mbps for Low Cost Fiber applications TTL synchronous I/O No external PLL components Triple PECL 100K serial outputs Dual PECL 100K serial inputs Low power: 350 mW (Tx), 650 mW (Rx) Compatible with fiber-optic modules, coaxial cable, and twisted pair media Built-In Self-Test Single +5V supply 28-pin SOIC/PLCC/LCC 0.8µ BiCMOS twisted pair). Standard HOTLink data rates range from 160-330 Mbits/second. Higher speed HOTLink is also available for high speed applications (160-400 Mbits/second), as well as for those Low Cost applications HOTLink-155 (150-160 Mbits/second operations). Figure 1 illustrates typical connections to host systems or controllers. Eight bits of user data or protocol information are loaded into the HOTLink transmitter and are encoded. Serial data is shifted out of the three differential positive ECL (PECL) serial ports at the bit rate (which is 10 times the byte rate). The HOTLink receiver accepts the serial bit stream at its differential line receiver inputs and, using a completely integrated PLL Clock Synchronizer, recovers the timing information necessary for data reconstruction. The bit stream is deserialized, decoded, and checked for transm...
