PHASEDETUP[6:1]
Phase Detector Up Signal Out to External PLL Cir-
cuit if SPEMPR Outputs DS3/E3 Data Without
Going Through Internal DS3/E3DJA.
If TSTMODE is high, these pin used for TSTMUX[5:0]
(test mode output).
Phase Detector Down Signal Out to External PLL
Circuit if SPEMPR outputs DS3/E3 Data Without
Going Through Internal DS3/E3DJA.
If TSTMODE is high, PHASEDETDOWN[4-1] used for
TSTMUX[9:6] (test mode output).
