9.9 to 12.5 Gbps 16:1 Multiplexer with Clock Multiplier Unit and Demultiplexer
with Clock Recovery Chip Set
VSC1237, VSC1238
The VSC1237 and VSC1238 is a complete high-
performance multiplexer/demultiplexer chip
set designed for 9.9-12.5 Gbps applications,
including SONET OC-192, SDH STM-64,
10GbE, G.975, G.709 and offering enhanced
capabilities specifically designed to address the needs of Ultra Long
Haul (ULH) and Long Haul (LH) fiber optic transmission systems.
The
VSC1237
is a 16:1 Multiplexer with an integrated Clock
Multiplier Unit. This device easily surpasses the jitter requirements
for SONET/SDH transmission systems. Integrated phase locked loop
circuits, including VCOs, are used for high speed clock generation,
jitter filtering and low-speed data transfer. This device offers
enhanced features, such as a integrated jitter filter PLL and a
selectable full/half-rate clock output, which is specifically designed to
be used in long haul and ultra long haul systems that utilize clocked
laser drivers or RZ signaling. The clock output features extremely low
clock-data skew variation, and can be disabled to save power.
The
VSC1238
is a 1:16 Demultiplexer (DMUX) with Clock and Data
Recovery (CDR) unit. This device is capable of direct recovery of
signals which are subject to various impairments/formats inherent in
ULH/LH systems, including poor Optical Signal to Noise Ratio (OSNR)
arising from optical amplification, distortion from Chromatic
Dispersion, Polarization Mode Dispersion / Differential Group Delay
(PMD/DGD), and RZ signaling. The highly sensitive front-end, precise
phase detector / decision circuit, and adaptive threshold features
eliminate the need for AGC amplifiers, post-amplifiers, filters, etc.
which are traditionally needed to recover these signals.
