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
