D Flip Flop
VWA-40-DFF-SD
10 – 40
Gb/s
Description
The
VWA 50002 AA
chip
is a D Flip Flop for high data
rate application, typically 10 to 40 (tbc) Gb/s. The chip
is designed in 0.18µm SiGe BiCMOS 150 GHz process.
The device has two high frequency differential inputs
(
NRZ_in and Clock) and one differential high frequency
output (DFF_Out). The chip is 50Ω single ended and
100
Ω differential in and out. The chip can be used
single in and out.
The input data stream is transferred to the output for
each clock rising edge. The output amplitude is 400 mV
pp single ended (800 mV differential pp).
The different parts of the chip are internally biased
using a voltage and currents reference circuit
(
Bandgap), in order to have the overall RF
characteristics of the chip, insensitive to the voltage
supply, the temperature and the process spread. An
enable input control pin is used to switch the chip ON
or OFF.
Three separate pins are used to bias the chip: one
dedicated to the reference circuit, the second for the
coder core (input buffers and coder core) and the last
for the 50Ω output driver. The 3 bias inputs can be
separately filtered / decoupled in order to optimize the
overall chip performances.
