PRODUCTION DATA
Table 6-30 lists the available JESD204B formats and corresponding valid sampling rate ranges for the ADC34RF5x. 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 6-29.
DECIMATION SETTING D (complex) | OUTPUT RESOLUTION (Bits) | L | M | F | S | MIN FS (Gsps) | MAX FS (Gsps) | RATIO [fSERDES/FS] |
---|---|---|---|---|---|---|---|---|
Bypass | 12(1) | 8 | 4 | 8 | 10 | 0.5 | 1.5 | 8 |
14 | 8 | 4 | 2 | 2 | 0.5 | 1.3 | 10 | |
14 | 4 | 4 | 2 | 1 | 0.5 | 0.65 | 20 |
(1) In full rate output, the two LSBs are truncated to a 12-bit output.
