MS
Mode Select. Control link mode-selection input requires an external pulldown or pullup resis-
tor. Set MS = low to select base mode. Set MS = high to select bypass mode.
Spread-Spectrum Enable. Serial link spread-spectrum enable input requires an external pull-
down or pullup resistor. The state of SSEN latches upon power-up or when resuming from
45
SSEN
power-down mode (PWDN = low). Set SSEN = high for Q2% spread spectrum on the LVDS
and control outputs. Set SSEN = low to use the LVDS and control outputs without spread
spectrum.
Data-Rate Select. Data-rate range-selection input requires an external pulldown or pullup resistor.
The state of DRS latches upon power-up or when resuming from power-down mode (PWDN =
46
DRS
low). Set DRS = high for TXCLKOUT_ frequencies of 8.33MHz to 16.66MHz (3-channel mode), or
6.25MHz to 12.5MHz (4-channel mode). Set DRS = low for TXCLKOUT_ frequencies of 16.66MHz
to 104MHz (3-channel mode), or 12.5MHz to 78MHz (4-channel mode).

EP
Exposed Pad. EP internally connected to AGND. MUST externally connect EP to the plane
supplying AGND for proper thermal and electrical performance.
