16MHZ CRYSTAL OSCILLATOR
Figure 15 shows a 16MHz crystal oscillator operating in the series
resonant mode using the SA5212A. The non-inverting input is fed
back to the input of the SA5212A in series with a 2pF capacitor. The
output is taken from the inverting output.

DIGITAL FIBER OPTIC RECEIVER
Figures 16 and 17 show a fiber optic receiver using off-the-shelf
components.
The receiver shown in Figure 16 uses the SA5212A, the Philips
Semiconductors 10116 ECL line receiver, and Philips/Amperex
BPF31 PIN diode. The circuit is a capacitor-coupled receiver and
utilizes positive feedback in the last stage to provide the hysteresis.
The amount of hysteresis can be tailored to the individual application
by changing the values of the feedback resistors to maintain the
desired balance between noise immunity and sensitivity. At room
temperature, the circuit operates at 50Mbaud with a BER of 10E-10
and over the automotive temperature range at 40Mbaud with a BER
of 10E-9. Higher speed experimental diodes have been used to
operate this circuit at 220Mbaud with a BER of 10E-10.
Figure 17 depicts a TTL receiver using the SA5212A and the
SA5214 fast amplifier system along with the Philips/Amperex PIN
diode. The system shown is optimized for 50 Mb/s Non Return to
Zero (NRZ) data. A link status indication is provided along with a
jamming function when the input level is below a
user-programmable threshold level.
