Transceiver Set-Up, 3.0 Vdc, -40 to +85
0
C
Notes:
1. OOK BER measured with no DS1 threshold (DS2 disabled), and data encoded for DC-balance with a run length limited to 4 bit periods.
2. ASK BER measured with a 25 mV DS1 threshold, DS2 threshold 6 dB below peak, and data encoded for DC-balance with a run length
limited to 4 bit periods.
3. Transmit/sleep to receive recovery time is for the period and signal level indicated, -40 to 60
o
C. Recovery time will increase at higher
temperatures, for longer transmit/sleep intervals and lower signal levels. See the
ASH Transceiver Designer’s Guide, Appendix D.
CAUTION: Electrostatic Sensitive Device. Observe precautions when handling.
