CY7C955 Datasheet (Cypress Semiconductor) - AX ATM-SONET/SDH Transceiver

CY7C955, AX ATM-SONET/SDH Transceiver

The Cypress Semiconductor CY7C955 is a Transceiver chip designed to carry ATM cells across SONET/SDH systems.

On the transmit side, ATM cells coming from the Utopia interface are being mapped into SONET/SDH frames and then serialized for transmission over fiber or twisted pair (through an optical mo
