Jitter Attenuator
(continued)
When the T7290A device is used only as a jitter attenuator, loopback 1 (LP1) should be active and the attenuator
must be placed in the transmit path (MODE1:2 = 01).
Table 6. Connectivity of Jitter Attenuator
* The jitter attenuator must be enabled after V
DD
exceeds 4.75 V during device powerup.
Jitter attenuator is powered down during this mode (see Table 8 under the Electrical Characteristics section).
Not used for normal operation.
