MAX19708: FAQ

Was this helpful?

Analog front-end IC MAX19705-MAX19708 operates in half-duplex mode. When switching from transmit mode(Tx) to receive mode (Rx), will there be any change at the TX DAC output pins (DP, IDN, QDP, and QDN)?

When MAX19705-8 is switched from Tx to Rx, the TX DAC bus is disabled and the existing DAC data cannot be maintained. If there is such requirement, MAX5864-MAX5865 can be used. From the MAX19705 datasheet…
