• Manufacturer: MX-COM, Inc.

MOTIENT
Operating Characteristics Notes:
1. At 25 ° C. Not including any current drawn from the modem pins by external circuitry other than the Xtal
2. Small signal impedance, at V
3. For a "+3 +3 -3 -3...." symbol sequence in RD-LAP mode, “+1 -1 ..” in MDC mode, at V
4. Measured at the TXOUT pin with the modem in Rx or Tx idle mode.
5. For optimum performance, measured at RXFB pin, for a "...+3 +3 -3 -3..." symbol sequence in RD-LAP
6. Timing for an external input to the XTAL pin.
7.
8. D0 - D7 pins.
