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.

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.
