1.2.1
The M21408/M21418/M21428 are designed to be operated with input signals as low as 100 mV or up to 2000 mV
differential peak to peak. The M21408/M21418/M21428 uses external 50Ω input termination resistors to match
100Ω differential impedance transmission lines for improved system level performance. The M21408/M21418/
M21428 recommended input circuits are shown in
Note that AC coupling is not required when the M21408/M21418/M21428 are driven by Mindspeed Broadcast
video devices.
