1.0625Gbps to 11.3Gbps,
SFP+ Dual-Path Limiting Amplifier
Register Descriptions
Receiver Control Register 1 (RXCTRL1)
Bits 7 and 6: RXDE[1:0]. These 2 bits are used to control deemphasis of the output waveform. See Table 5 for the bit
settings and corresponding deemphasis levels.
Bit 4: SOFTRES. When this bit is set to 1 during a 3-wire interface write operation, all registers are set to the default
state when CSEL goes low.
Bits 3 and 2: BW[1:0]. When RATE_SEL = 0, these 2 bits control the bandwidth of the limiting amplifier. See Table 1 for
the settings and corresponding filter selection.
Bit 1: RATE_SEL. RATE_SEL selects between the low bandwidth data path (1.0625Gbps to 4.25Gbps) and the high
bandwidth data path (4.25Gbps to 11.3Gbps). When RATE_SEL is set to 1, the high bandwidth path is chosen. When
RATE_SEL is set to 0, the low bandwidth path is chosen.
