NOTES:
1. Does not include Miller-multiplied capacitance of input device.
2. Noise performance measured differential. Single-ended output noise is higher due to CM noise.
3. PSRR is output referenced and is circuit board layout dependent at higher frequencies. For best performance use a RF filter in V
CC
line.
4. This implies that the SA5223 gain will change 1dB (10%) in the absence of data for 1ms (i.e., can handle bursty data without degrading Bit
Error Rate (BER) for 100,000 cycles at 100MHz).
