Nominal VCO Center Frequency (CSU
and CRU)
TX and RX VCO frequency
([T/R]X_VCO_Range = 00)
TX and RX VCO frequency
([T/R]X_VCO_Range = 01)
TX and RX VCO frequency
([T/R]X_VCO_Range = 10)
TX and RX VCO frequency
([T/R]X_VCO_Range = 11)
Frequency difference at which the receive
PLL goes out of lock (CRU_REFCLK
compared to the divided down VCO
clock). LOCKDET is de-asserted when
PLL goes out of lock.
Frequency difference at which receive
PLL goes into lock (CRU_REFCLK com-
pared to the divided down VCO clock).
LOCKDET is asserted 0.5 ms after PLL
goes into lock.

VCO frequency guaranteed
with + 600 ppm offset
LOCKDET “into lock” status is
only valid when the incoming
data is within +800 ppm of the
VCO clock.
Note the VCO clock is a multiple of the
CRU_REFCLK when out of lock.
After the release of RSTB,
with device already powered
up and with a valid
CRU_REFCLK. Guaranteed
but not tested.
