FUNCTION NAME
Boost (dB) = 1dB + <gain value> * 0.8dB
0x0: 1dB boost at 800MHz
0xC: 10.6dB boost at 800MHz (default)
0xF: 13dB boost at 800MHz
Boost (dB) = 1dB + <gain value> * 0.8dB
0x0: 1dB boost at 800MHz
0xC: 10.6dB boost at 800MHz (default)
0xF: 13dB boost at 800MHz
When a 25MHz to 165MHz clock is applied to the selected
channel’s clock input, this function will output a PRBS7
pattern on the TX pins.
0: Normal operation (test patterns disabled)
1: PRBS7 pattern
2: Low frequency toggle (0000011111…)
3: High frequency toggle (1010101010…)
Note: When switching from the high frequency toggle
pattern to the low frequency toggle pattern, you must first
select normal operation.
Enables PRBS7 error counter in registers 0x0A to 0x0C.
0: Disable PRBS7 Error Counter
1: Enable PRBS7 Error Counter
PRBS7 Error Counter of Link 0. Saturates at 0xFF. Reading
this register clears this register at end of read
PRBS7 Error Counter of Link 1. Saturates at 0xFF. Reading
this register clears this register at end of read
PRBS7 Error Counter of Link 2. Saturates at 0xFF. Reading
this register clears this register at end of read
Selects between 4 PLL bandwidth settings
0: 4MHz (silicon default)
1: 2MHz
2: 1MHz (recommended default)
3: 500kHz
1MHz provides slightly better performance with high jitter/
high noise signals.
Keep set to 000100 binary.
