155Mb/s / 622Mb/s Transmitter (Multiplexer) with Clock Generation

The MC10SX1405 transmitter (Tx) chip is an integrated serialization SONET OC–3 (155.52Mb/s) and OC–12 (622.08 Mb/s) interface device. It generates the line rate clock and performs parallel–to–serial conversion in conformance with SONET/SDH transmission standards. High performance and low power is achieved with MOSAIC VTM, Motorola’s most advanced high–performance silicon Bipolar process. A companion de–serialization (Rx) chip, the SX1401, is also available.

• Selectable eight or four bit parallel interface
• Performs parallel–to–serial conversion of four 38.88 Mbit/s or eight 19.44 Mbit/s inputs to a 155.52 Mbit/s OC3 serial data output
• Performs parallel–to–serial conversion of eight 77.76 Mbit/s inputs to a 622.08 Mbit/s OC12 serial data output
• Integrated PLL and VCO to generate the line–rate clock from a sub–rate reference clock
• Multiple configurations for parallel interface timing provide system design versatility
• Provides PLL Frequency Control Monitor and Out–of–Lock Indicator
• Provides parity verification of the OC3/OC12 serial output stream
• Single supply operation (+5V)

APPLICATIONS
• SONET/SDH–based transmission systems, modules, test equipment
• ATM using SONET
• Add drop multiplexers
• Other (non–SONET) data rate transmission systems
