Description

The S3086 Continuous Rate Clock Recovery Unit

(CRU) is a variable rate clock recovery interface

device. This device is suitable for use in

applications such as SONET/SDH, Fibre Channel,

Fast Ethernet, HDTV, ESCON, Gigabit Ethernet,

and DS-3. The chip performs all necessary clock

recovery functions in conformance with the

Telcordia 253, IEEE 802.3, and SMPTE 292/184

transmission standards.

The S3086 CRU is capable of accepting a

scrambled 30 Mbps to 2.7 Gbps serial NRZ data

stream. It can derive a data clock from the data

stream and output the data stream retimed and

aligned with a companion serial bit clock. The

S3086 achieves its continuous rate capability in

a piece-wise continuous manner. This means

that the full operating range is provided

through the selection of one of twenty six (26)

overlapping bands which are uniquely

identified/programmed a by 5-bit band select

input bus. The S3086 is implemented using

AMCC’s proven Phase Lock Loop (PLL)

technology. Figure 1 shows a typical network

application for the S3086.

TEIB

An external reference oscillator should be used

for applications, including SONET/SDH, in which

continuous down-stream clocking is a

requirement under Loss-of-Signal (LOS)

conditions.

The S3086 utilizes an on-chip PLL which

consists of a phase detector, a loop filter, and a

Voltage Controlled Oscillator (VCO). The phase

detector compares the phase relationship

between the VCO output and the serial data

input. A loop filter converts the phase detector

output into a smooth DC voltage, and the DC

voltage is input to the VCO whose frequency is

varied by this voltage.
