Daisy chain multiple HMC542BLP4E?

Can multiple HMC542BLP4E be daisy-chained together?  From the description of the Serial Output pin and the Latch Enable pin, this seems to be an intended feature but it's not explicitly described in the datasheet.

    Hi Kevin,

    The serial output is served as a monitor/read, with 8 clock cycle delayed from the serial input. The HMC542B is design targeted for cascading the HMC542B with Dattn out of pre-stage to the Dattn in of the cascaded stage, with LE to control the Dattn setting for each HMC542B.

    Below is the functional diagram of our serial control circuitry used in the HMC542BLP4E, as shown in the datasheet, and our suggested serial control configuration for cascaded application:

    Best Regards,

    MN
