GSL304
GSL304
Ultra Low Power Mobile EMI Reduction IC
Product Description
The GSL304 is a versatile 1x Active EMI
management IC designed to provide system wide
reduction of Electromagnetic Interference (EMI) and
Radio Frequency Interference (RFI) from clock and
data sources. The GSL304 allows significant system
cost savings by reducing the number of circuit board
layers, ferrite beads, shielding and other passive
components that are traditionally required to pass
EMI regulations.
The GSL304 family of mobile active EMI
management ICs is unique in it’s design and is
based on GS’s proprietary “SaΦic” phase controlled
Active EMI management technology. This allows
operation on aperiodic as well periodic signals. By
the precise placement of the edges of the
reconstructed input signal, the peak energy of the
output is distributed over a wider and controlled
energy band thereby significantly lowering system
EMI compared to the typical narrow band signal
produced by oscillators and most frequency
generators.
The GSL304 has an input frequency range of
10MHZ to 50MHz over a wide voltage range of
1.65V to 3.6V. The device can be placed in “power
save mode” by setting the PDB pin to GND where in
it draws typically 0.1uA and also stes the MODOUT
pin to a High-Z state. The device has two “deviation
control pins” SS1 and SS0 to allow flexibility and
optimization of both EMI compliance as well as in
system design.
