155Mb/s / 622Mb/s Receiver
(Demultiplexer) with Clock
Recovery
The MC10SX1401 receiver (Rx) chip is an integrated de–serialization
SONET OC–3 (155.52 Mb/s) and OC–12 (622.08 Mb/s) interface device.
It performs the data and clock recovery and serial–to–parallel conversion
functions in conformance with SONET/SDH transmission standards.
High performance and low power is achieved with MOSAIC V™,
Motorola’s most advanced high–performance silicon Bipolar process. A
companion serialization (Tx) chip, the SX1405, is also available.
• Recovers a 155.52/622.08 MHz internal clock from an OC3/OC12 data
stream
• Samples, quantizes and demultiplexes the input signal into a parallel
TTL data stream
• Generates an EVEN parity bit with the demultiplexed data
• Provides a 155.52 MHz differential PECL timing reference clock
• No external input reference clock is required
• Detects the peak amplitude of the Rx signal and generates a
proportional DC voltage
• Provides PLL Frequency Control Monitor and Out–of–Lock Indicator
• Selectable eight or four bit parallel interface
• 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
