GENERAL DESCRIPTION
The function of the S3029 clock synthesis and recov-
ery unit is to derive high speed timing signals for
SONET/SDH-based equipment. The S3029 is imple-
mented using AMCC’s proven Phase Locked Loop
(PLL) technology.
The S3029 receives four STS-3/STM-1 scrambled NRZ
signals and recovers the clock from the data and
generates a 155 MHz transmit clock. The chip out-
puts a differential PECL bit clock and retimed data.
Figure 1 shows a typical network application.
The S3029 utilizes five on-chip PLLs which consist of
a phase detector, a loop filter, and a voltage con-
trolled 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 fre-
quency is varied by this voltage. A block diagram is
shown in Figure 2. There is a single clock multiplier
PLL which generates a 155 MHz transmit clock from
a 19.44 or 51.84 MHz input.
