Bit 5: Local Oscillator Edge (XOEDGE). This bit specifies the significant clock edge of the local oscillator clock
signal on the REFCLK input pin. The faster edge should be selected for best jitter performance. See Section 7.3.
0 = Rising edge
1 = Falling edge
Bit 4: Free-Run Holdover (FRUNHO). When this bit is set to 1 the T0 DPLL holdover frequency is set to 0ppm so
the output frequency accuracy is set by the external oscillator accuracy. This affects both mini-holdover and the
holdover state.
0 = Digital holdover
1 = Free-run holdover, 0ppm
Bit 2: SONET or SDH Frequencies (SONSDH). This bit specifies the clock rate for input clocks with FREQ = 0001
in the ICR registers (20h to 28h). During reset the default value of this bit is latched from the SONSDH pin. See
Section 7.4.2.
0 = 2048kHz
1 = 1544kHz

Bit 7: Digital Alternate Frequency (DIG2AF). Selects alternative frequencies.
0 = Digital2 N x E1 or N x DS1 frequency specified by DIG2SS and MCR7:DIG2F.
1 = Digital2 6.312MHz, 10MHz, or N x 19.44MHz frequency specified by DIG2SS and MCR7:DIG2F.
Bit 6: Digital2 SONET or SDH Frequencies (DIG2SS). This bit specifies whether the clock rates generated by the
Digital2 clock synthesizer are multiples of 1.544MHz (SONET compatible) or multiples of 2.048MHz (SDH
compatible) or alternate frequencies. The specific multiple is set in the DIG2F field of the MCR7 register. When
RST = 0 the default value of this bit is latched from the SONSDH pin.
DIG2AF = 0:
0 = Multiples of 2048kHz
1 = Multiples of 1544kHz
DIG2AF = 1:
6.312MHz, 10MHz, or N x 19.44MHz
Bit 5: Digital1 SONET or SDH Frequencies (DIG1SS). This bit specifies whether the clock rates generated by the
Digital1 clock synthesizer are multiples of 1544kHz (SONET compatible) or multiples of 2048kHz (SDH
compatible). The specific multiple is set in the DIG1F field of the MCR7 register. When
RST = 0 the default value of
this bit is latched from the SONSDH pin.
0 = Multiples of 2048kHz
1 = Multiples of 1544kHz
