Preliminary Information
MH88628
AC Electrical Characteristics
Characteristics
* Typical figure are at 25
°
C with nominal
+
5V supplies and are for design aid only.
AC Electrical Characteristics are over recommended operating conditions unless otherwise stated.
Notes:
Impedance set by external network of 600
or 900
default.
External network for test purposes consists of 2200
+ 8200
// 11.5nF between pins Z1 and Z2, the equivalent Zin has 1/10
th
the impedance
and is equivalent o 220
+820
// 115nF.
Test condition uses a Zin value of 600
, 900
and the above external network.
Test conditions use a transmit and receive gain set to 0dB default and a Zin value of 600
unless otherwise stated.
“Ref” indicates reference impedance which is equivalent to the termination impedance.
“Net” indicates network balance impedance.
Refer to Table 1, 2 for TX, RX gain adjustment.
