Multiplexer/Demultiplexer Chipset
2.5Gb/s 16-Bit
Features
Functional Description
The VSC8061 and VSC8062 are high-speed interface devices capable of data rates up to 2.5Gb/s. The
devices are fabricated in gallium arsenide using the Vitesse H-GaAs E/D MESFET process to achieve high-
speed and low power dissipation. For ease of system design using these products, both devices use industry-
standard -5.2V and -2V power supplies, and have ECL-compatible I/O for parallel data interfaces. Typical
applications include telecommunication transmission and instrumentation.
VSC8061 Multiplexer
The VSC8061 consists of a 16:1 multiplexer circuit, a phase detector, and a timing circuit which generates
a divide-by-16 clock from the high-speed clock input. The 16:1 multiplexer accepts 16 parallel single-ended
ECL compatible inputs (D0...D15) at data rates up to 156Mb/s and bitwise serializes them into a 2.5Gb/s serial
output (DO/DON). The internal timing of the VSC8061 is referenced to the negative going edge of the high-
speed clock true input (CLK). This clock is divided by 16 and is provided as an output (CLK16/CLK16N). The
setup and hold time of the parallel inputs (D[0:15]) are specified with respect to the falling edge of CLK16, so
that CLK16/CLK16N can be used to clock the data source of D[0:15]. The on-chip phase detector monitors the
phase relationship between the internally generated divide-by-16 clock and an externally supplied low-speed
reference clock input (DCLK/DCLKN). Phase difference between these two clock signals generates an up or
down output (U, D) for phase lock applications. The phase detector can be used as part of an external Phase
Locked Loop (PLL) to implement a clock multiplication function.
In applications where a 2.5GHz system clock is provided, and the phase detector function is not required, it
is recommended to connect one side of the DCLK/DCLKN input to V
TT
through a 50
resistor. The U and D
output can be left open and unused.
VSC8062 Demultiplexer
The VSC8062 consists of a 1:16 demultiplexer and timing circuitry which generates a divide-by-16 clock
from the high-speed clock input. The demultiplexer accepts a serial data stream input (DI/DIN) at up to 2.5Gb/s
and deserializes it into 16 parallel single-ended ECL compatible outputs (D[0:15]) at data rates up to 156 Mb/s.
The internal timing of the VSC8062 is referenced to the negative going edge of the high-speed clock true input
(CLK). This clock is divided by 16 and provided as an output (CLK16/ CLK16N). The timing parameters of the
parallel data outputs (D[0:15]) are specified with respect to the falling edge of CLK16, so that CLK16/CLK16N
can be used to clock the destination of D[0:15].
