The MAX3873 is a compact, low-power 2.488Gbps/ 2.67Gbps clock-recovery and data-retiming IC for SDH/SONET applications. The phase-locked loop (PLL) recovers a synchronous clock signal from the serial NRZ data input. The input data is then retimed by this recovered clock, providing a clean data output.
The MAX3876 is a compact, low-power clock recovery and data retiming IC for 2.488Gbps SDH/SONET appli-cations. The fully integrated phase-locked loop (PLL) recovers a synchronous clock signal from the serial NRZ data input. The data is retimed by the recovered clock. Differential CML outputs are provided for both
Channelized SONET Overview. Synchronous Optical Network (SONET) is an American National Standards Institute (ANSI) specification format used in transporting digital telecommunications services over optical fiber. Synchronous Digital Hierarchy (SDH) is the international equivalent of SONET.
The MAX3881 deserializer with clock recovery is ideal for converting 2.488Gbps serial data to 16-bit-wide, 155Mbps parallel data for SDH/SONET applications.
Before configuring Channelized SONET/SDH, be sure that the following tasks and conditions are met: You have at least one of the following SPAs installed in your chassis: Cisco 1-Port Channelized OC-3/STM-1 SPA. Cisco 1-Port Channelized OC-12/DS0 SPA. Cisco 1-Port Channelized OC-48/STM-16 SPA.
settings to settings, such as the clock recovery mode ACR/DCR, and the frames per packet, etc. A typical setting of using DCR clock mode with 1 frame per packet will result in 0.8ms per LER and 10ns per LSR. For an E1 SAToP PW passing through 12 nodes, the total latency will be 1.6ms (0.8ms x2 +10ns x10) approximately.
Bit recovery is done by first recovering the service clock along with the noise from the transmission medium. Since the majority of this noise is typically over 10 Hz (possibly in the MHz), a high bandwidth recovery function is used.
Feb 1, 2000 This paper presents the architectural concepts behind a versatile VLSI device that maps ATM, IP, and/or traditional T1/T3 traffic streams into SONET/SDH transport signals ranging from OC-1 to...

SDH/SONET Timing. Overview. Parametric Search. Ordering. Support. Proper operation of SONET/SDH equipment requires the recovery of a line timed source and the ability to synthesize SONET/SDH interface clocks, tributary clock families and SBI or Telecom bus clocks locked to a reference.
For interfaces such as SONET/SDH that can use different clock sources, you can configure the source of the transmit clock on each interface. The source can be internal or external. The default source is internal, which means that each interface uses the routers internal Stratum 3 clock.
DS3 Channelized Interface The physical layer DS3 Channelized Interface object represents a high-o rder SONET/SDH DS3 circuit. Clocking The SONET port TX clock source where the internal keyword sets the internal clock (line, internal). The line keyword sets the clock recovered from the line (this is the default).

Differential Clock Recovery (DCR) is an alternative method to ACR to maintain the service clock across the packet network for a circuit emulated service. DCR is supported on: 16-port T1/E1 ASAP Adapter card. 32-port T1/E1 ASAP Adapter card. 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card (DS1/E1 channels)
Integrated clock recovery & synthesis allows direct interface to low-cost optical transceivers Integrated clock synthesis generates line clock from 77.76 MHz reference Complies with Bellcore, ANSI, and ITU specifications for Jitter Tolerance and Jitter Generation High order path processing and alignment to STS-1/AU-3/TU-3 level
Nov 2, 2006 Introduction. This document reviews the basic differences in the framing used with Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) in an Asynchronous Transfer Mode (ATM) environment, and in a Packet over SONET (POS) environment.
Recover Clock and Synchronization Legacy TDM devices require a synchronized clock to function, but the packet switched network by nature is not synchronous. The pseudowire emulation mechanism must regenerate the original TDM timing accurately across the packet network. Available Pseudowire Types.
