7.3.1 Linear Equalization

The DS160PR410 receivers feature a continuous-time linear equalizer (CTLE) that applies high-frequency boost and low-frequency attenuation to help equalize the frequency-dependent insertion loss effects of the passive channel. Table 1 shows available equalization boost through EQ0_ADDR0 and EQ1_ADDR1 control pins, when in Pin Control mode (EN_SMB = L0).

Table 1. Equalization Control Settings

EQUALIZATION SETTING TYPICAL EQ BOOST
INDEX EQ1_ADDR1 EQ0_ADDR0 @ 4 GHz @ 8 GHz
0 L0 L0 –0.3 –0.8
1 L0 L1 0.4 1.3
2 L0 L2 3.3 5.7
3 L0 L3 3.8 7.1
4 L1 L0 4.9 8.4
5 L1 L1 5.2 9.1
6 L1 L2 5.4 9.8
7 L1 L3 6.5 10.7
8 L2 L0 6.7 11.3
9 L2 L1 7.7 12.6
10 L2 L2 8.7 13.6
11 L2 L3 9.1 14.4
12 L3 L0 9.4 15.0
13 L3 L1 10.3 15.9
14 L3 L2 10.6 16.5
15 L3 L3 11.8 17.8

The equalization of the device can also be set by writing to SMBus/I2C registers in slave or master mode. Refer to the DS160PR410 Programming Guide (SNLU255) for details.
