CY7B933-SC

Overview

The CY7B933-SC is a HOTLink receiver integrated circuit manufactured by Infineon Technologies, housed in a 28-pin SOIC package. It operates on a single +5V supply and supports data rates from 160 Mbps to 400 Mbps. The device features dual PECL differential serial inputs (INA±/INB±) and TTL synchronous parallel outputs (Q0-Q7). Key specifications include an embedded PLL for clock synchronization, 8B/10B decoding capability, and Built-In Self-Test (BIST) functionality.

Feature Summary

• Supports high-speed point-to-point serial communication links using fiber-optic, coaxial, or twisted pair media.
• Integrates an embedded phase-locked loop (PLL) clock synchronizer for timing recovery without external components.
• Includes built-in self-test (BIST) logic for verifying transmitter, receiver, and link integrity.

Applications

• Interconnecting workstations and servers via high-speed serial links.
• Mass storage system interconnects requiring long-distance data transfer.
• Video transmission equipment and multimedia signal routing.

Procurement Notes

Verify the specific suffix 'SC' corresponds to the 28-SOIC package variant when sourcing replacements. Confirm that the component meets the required operating temperature range of 0°C to 70°C for your application environment. Check for end-of-life status as this product line may be discontinued by the manufacturer.

Selection Notes

Select the CY7B933-SC when a TTL-compatible interface is required alongside PECL differential inputs. Ensure the host system provides a reference clock frequency compatible with the REFCLK input requirements. Verify that the data rate falls within the 160–400 Mbps operational window supported by this specific device revision.

Part Context

This component belongs to the HOTLink family of transceivers designed for Fibre Channel and ESCON compliance. It functions as the receiver counterpart to the CY7B923 transmitter. The series enables replacement of parallel interfaces with robust serial connections for high-bandwidth applications.
