required to reach a balanced mark/space ratio (i.e.,
50%). This permits the use of scrambled data as found
in SONET and SDH transmissions.
The limiting amplifier limits the outputs of the equalizer so
all frequencies are at the same output voltage level.
Connect the EN pin to V
Connect the EN pin to GND to disable the equalizer core
when valid data is not present to save power. When EN is
low, the outputs are static with approximately 30mV
differential. This pin must be connected to V
The MAX3803 is packaged in a 2.5mm × 2mm, 5 × 4
chip-scale package (USCP). The six center ball positions
(B2, B3, B4, C2, C3, C4) are not populated, leaving four-
teen perimeter balls. This package does not require
underfill over an ambient temperature range of 0°C to
+85°C. Thermal dissipation is provided through the
GND connection. Go to Maxim’s website, www.maxim-
ic.com, for the latest packaging information and details
about UCSP layout and handling.
For best performance, use good high-frequency layout
techniques. Filter voltage supplies, keep ground con-
nections short, and use multiple vias where possible.
Use controlled-impedance transmission lines to inter-
face with the MAX3803 high-speed inputs and outputs.
Power-supply decoupling should be placed as close to
the V
input signals from output signals.
