4.5.11 PD_RESTORE_LOSb_CONFIG

Configuration and Status Register.

3:0

amp_cntrl_def_bnk0

0x7

Default amplitude control for bank 0. When the multifunction pin is configured

as Amplitude Select, this field defines the single-ended output amplitude of the

Bank 0 (CLK[3:0]) when the pin = 0. When the multifunction pin is configured

as Slew Rate Selection, this field determines the amplitude of bank 0

(CLK[3:0]).

0x0 = 625mV

0x1 = 650mV

0x2 = 675mV

0x3 = 700mV

0x4 = 725mV

0x5 = 750mV

0x6 = 775mV

0x7 = 800mV

0x8 = 825mV

0x9 = 850mV

amp_cntrl_def_bnk0 (continued)

0xA = 875mV

0xB = 900mV

0xC = 925mV

0xD = 950mV

0xE = 975mV

0xF = 1000mV

Reserved

ck_acquire_rb

0x0

Clock acquired read-back. This bit indicates if a clock was ever detected

(LOSb de-asserted) for the current power cycle.

0 = Clock never acquired

1 = Clock acquired once before

pd_restoreb

0x1

Save configuration in power-down. This bit determines the behavior of the

device when the PWRGD_PWRDNb pin is asserted low. This bit is

automatically returned to 1 after PWRGD_PWRDNb is toggled 1-0-1 with the

bit set to 0.

0 = Config Cleared

1 = Config Saved

sdata_time_out_enable

0x1

Enable SMB time out monitoring SDATA. This bit enables a timeout for the

SMBus data path. This timeout monitor is in addition to the mandatory SCLK

timeout monitor. These monitors release a hung SMBus.

0 = Disable SDATA time out

1 = Enable SDATA time out

los1b_rb

0x0

Real-time read back of CLKIN1 clock detect. This bit provides a real-time

status of the CLKIN1 input. The default value assumes CLKIN1 is not present.

0 = LOS event detected (no CLKIN1 detected)

1 = No LOS event detected (CLKIN1 detected)

los0b_rb

0x0

Real-time read back of CLKIN0 clock detect. This bit provides a real-time

status of the CLKIN0 input. The default value assumes CLKIN0 is not present.

0 = LOS event detected (no CLKIN0 detected)

1 = No LOS event detected (CLKIN0 detected)
