ISAC-SX TE
PSB 3186
Description of Functional Blocks
1:1
S Bus
Note: up to 10 pF capacitors are optional for noise reduction

External Circuitry for Symmetrical Receivers
Between each receive line and the transformer a 10 k W resistor is used. This value is
split into two resistors: one between transformer and protection diodes for current limiting
during the 96 kHz test, and the second one between input pin and protection diodes to
limit the maximum input current of the chip.
With symmetrical receivers no difficulties regarding LCL measurements are observed;
compensation networks thus are obsolete.
In order to comply to the physical requirements of ITU-T recommendation I.430 and
considering the national requirements concerning overvoltage protection and
electromagnetic compatibility (EMC), the ISAC-SX TE may need additional circuitry.
