CY7B9234-270JC

Overview

The CY7B9234-270JC is a HOTLink transmitter manufactured by Cypress Semiconductor Corp. It functions as a point-to-point communication building block designed to transfer data over high-speed serial links using fiber, coaxial cable, or twisted pair media. The device supports standard HOTLink data rates ranging from 160 to 330 Mbits/second and is compliant with protocols such as Fibre-Channel, IBM ESCON, DVB-ASI, and ATM. It utilizes an 8B/10B coding scheme and features TTL synchronous I/O without requiring external phase-locked-loop components.

Feature Summary

• Supports high-speed serial data transmission over various physical media including fiber-optic modules, coaxial cables, and twisted pairs.
• Integrates built-in self-test (BIST) capabilities for system verification.
• Operates on a single +5V supply with low power consumption characteristics.
• Provides triple PECL 100K serial outputs and dual PECL 100K serial inputs.

Applications

• Fibre-Channel compliant interconnects
• IBM ESCON compliant systems
• DVB-ASI compliant applications
• Asynchronous Transfer Mode (ATM) networks

Procurement Notes
