7.3.6.3 JESD204B Frame Assembly in Bypass Mode

Table 7-36 lists the available JESD204B formats and corresponding valid sampling rate ranges for the ADC32RF5x. The sampling rates are limited by the minimum and maximum SERDES line rate as well as ADC sampling clock frequencies. The JESD204B frame assembly for the different lanes is shown in Table 7-33.

When internal digital averaging is used, the output resolution is automatically adjusted from 14-bit to 16-bit to avoid quantization noise limitation.

Table 7-32 JESD Mode Options: Bypass Mode

14/16(2)82240.52.65

(1) In full rate output, two LSBs are truncated to a 12-bit output.

(2) When using digital averaging the output resolution changes to 16-bit.
