3.3 TRANSMIT PATH SPECIFICATIONS
Table 3. Transmit Path Specifications
Unless otherwise noted, typical specifications apply for VCC=5 Volts, temperature=2 7× C, nominal process and
current. Maximum and minimum performance is with VCC ±5%, -40 =< T

<19>Minimum DS frequency is 36*4.3125kHz=155.25kHz and as such the coupling capacitors between RXINP/N and RXDCIP/N
<20>Minimum DS frequency is 7*4.3125kHz=30.1875kHz and as such the coupling capacitors between RXINP/N and RXDCIP/N
must be such that the high pass pole is ~15kHz (typical). With a 1kW minimum input impedance at RXDCIP/N this gives a capacitor
value of about 10nF. This gives a 1t settling time of 10ms.To guarantee 12-bit performance a minimum of 10t settling gives 100ms.
must be such that the high pass pole is ~3kHz (typical). With a 1kW minimum input impedance at RXDCIP/N this gives a capacitor
value of about 53nF. This gives a 1t settling time of 53ms.To guarantee 12-bit performance a minimum of 10t settling gives 530ms.
