CY7B923/CY7B933 HOTLink Transmitter/Receiver Features Functional Description Fibre Channel-compliant The CY7B923 HOTLink transmitter and CY7B933 HOTLink receiver are point-to-point communications building blocks that IBM ESCON -compliant transfer data over high-speed serial links (fiber, coax, and twisted pair). Standard HOTLink data rates range from 160 to 330 Mbps. DVB-ASI-compliant Higher speed HOTLink is also available for high-speed applica- ATM-compliant tions (160 to 400 Mbits/second). Figure 1 illustrates typical connections to host systems or controllers. 8B/10B-coded or 10-bit unencoded Eight bits of user data or protocol information are loaded into the Standard HOTLink : 160 to 330 Mbps HOTLink transmitter and are encoded. Serial data is shifted out of the three differential PECL serial ports at the bit rate (which is High-speed HOTLink: 160 to 400 Mbps for high-speed ten times the byte rate). applications The HOTLink receiver accepts the serial bit stream at its differ- Transistor-transistor logic (TTL)-synchronous I/O ential line receiver inputs and, using a completely integrated PLL No external phase locked-loop (PLL) components clock synchronizer, recovers the timing information necessary for data reconstruction. The bit stream is deserialized, decoded, Triple positive emitter coupled logic (PECL) 100 K serial and checked for transmission errors. Recovered bytes are outputs presented in parallel to the receiving host along with a byte-rate clock. Dual PECL 100 K serial inputs The 8B/10B encoder/decoder can be disabled in systems that Low-power: 350 mW (Tx), 650 mW (Rx) already encode or scramble the transmitted data. I/O signals are Compatible with fiber-optic modules, coaxial cable, and twisted available to create a seamless interface with both asynchronous pair media FIFOs (that is, CY7C42X) and clocked FIFOs (that is, CY7C44X). A BIST pattern generator and checker allows testing Built-in self-test (BIST) of the transmitter, receiver, and the connecting link as a part of a system diagnostic check. Single +5-V supply HOTLink devices are ideal for a variety of applications where a 28-pin small outline integrated circuit (SOIC)/plastic leaded parallel interface can be replaced with a high-speed chip carrier (PLCC) point-to-point serial link. Applications include interconnecting Pb-free packages available workstations, servers, mass storage, and video transmission equipment. 0.8- bipolar complementary metal oxide semiconductor (BiCMOS) CY7B923 Transmitter Block Diagram Cypress Semiconductor Corporation 198 Champion Court San Jose, CA 95134-1709 408-943-2600 Document Number: 38-02017 Rev. *K Revised November 7, 2017CY7B923/CY7B933 CY7B933 Receiver Block Diagram Figure 1.
