Overview
The CY7B923-JXI is a HOTLink transmitter component manufactured by Cypress Semiconductor Corp, designed for point-to-point high-speed serial data communication. It operates within the standard HOTLink series, supporting data rates from 160 to 330 Mbps. The device utilizes 8B/10B encoding or unencoded transmission modes and features TTL synchronous I/O interfaces. Power consumption is specified at 350 mW with a single +5V supply. The chip integrates a clock generator, input register, encoder, shift register, and triple PECL differential outputs. It supports hot-swapping and includes built-in self-test logic. The component is available in 28-pin SOIC, PLCC, and LCC packages.
Feature Summary
- Supports Fibre-Channel, IBM ESCON, DVB-ASI, and ATM protocols
- Integrates Built-In Self-Test (BIST) functionality
- Features triple PECL differential serial outputs
- Operates without external phase locked-loop components
Applications
- Fiber optic communication equipment
- Workstation to mass storage interconnects
- Video on demand systems
- Voice and image multimedia transmission devices
Procurement Notes
Verify the specific suffix 'JXI' against official Cypress documentation to confirm package type and temperature range. Ensure compatibility with existing FIFO interfaces and power supply requirements before procurement.
Selection Notes
Select this model for applications requiring standard HOTLink speeds up to 330 Mbps. Consider the -400 series if higher throughput up to 400 Mbps is necessary. Verify that the system supports the required TTL synchronous I/O timing.
Part Context
The CY7B923 is part of the HOTLink family of transceivers developed by Cypress Semiconductor. It serves as the transmitter counterpart to the CY7B933 receiver, enabling high-speed serial links over fiber, coaxial cable, or twisted pair media.
Replacement Considerations
Check for direct pin-compatible replacements within the same HOTLink family. Verify that any substitute maintains the 160-330 Mbps speed grade and PECL output characteristics.
