S3076

MULTI-RATE SONET/SDH CLOCK RECOVERY UNIT

BiCMOS PECL CLOCK GENERATOR

FEATURES

GENERAL DESCRIPTION

The function of the S3076 clock recovery unit is to

derive high speed timing signals for SONET/SDH-

based equipment. The S3076 is implemented using

AMCC’s proven Phase Locked Loop (PLL) technology.

Figure 1 shows a typical network application.

•

SiGe BiCMOS technology

Complies with Bellcore and ITU-T specifica-

tions for jitter tolerance, jitter transfer and

jitter generation

•

On-chip high frequency PLL with internal

loop filter for clock recovery

The S3076 receives an OC-48, OC-24, OC-12, OC-3,

Fibre Channel or Gigabit Ethernet scrambled NRZ sig-

nal with FEC capability up to 8 bytes per 255-byte

block and recovers the clock from the data. The chip

outputs a differential bit clock and retimed data.

Supports clock recovery for:

OC-48 (2488.32 Mbps) (with FEC)

Fibre Channel (2125 Mbps) (with FEC)

OC-24 (1244.16 Mbps) (with FEC)

Gigabit Ethernet (1250 Mbps) (with FEC)

Fibre Channel (1062.5 Mbps) (with FEC)

OC-12 (622.08 Mbps) (with FEC)

The S3076 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 con-

verts 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. A block

diagram is shown in Figure 2.

OC-3 (155.52 Mbps) (with FEC) NRZ data

•

Selectable reference frequencies

19.44 MHz or 155.52 MHz

(or equivalent Fibre Channel/

Gigabit Ethernet frequencies)

Lock detect—monitors frequency of

incoming data

•

Low-jitter serial interface

+3.3 V supply

Compact 48 pin TQFP TEP package

Typical power 620 mW

Available in Die form also
