7 Parameter Measurement Information

7.1 Over-Range Functional Characteristics

Unless otherwise noted, these specifications apply for all supply and temperature conditions.

PARAMETER DESCRIPTION AND TEST CONDITIONS VALUE UNIT
OVRTH Over-range detection threshold
Configurable via SPI 		–48.16 (min) and 0 (max) dBFS
OVRTHS Over-range detection threshold step
Expressed as the change in the total code range outside of which an over-range event occurs. Half of the step value is changed at the upper boundary of the code range and half is changed at the lower boundary.		 256 codes

7.2 Input Clock Divider and Clock Phase Adjustment Functional Characteristics

Unless otherwise noted, these specifications apply for VA3.0 = 3.0 V; VA1.8 = 1.8 V; VA1.2 = VD1.2 = 1.2 V; FCLKIN = FS = 370 MSPS. Typical values are at TA = +25°C.

PARAMETER DESCRIPTION AND TEST CONDITIONS TYP LIMIT UNIT
CLKDIV Input CLKIN divider factor
Configurable via SPI		 1 (default), 2, 4, or 8
NФC Number of available coarse phase adjustment steps 2 × CLKDIV
ФC Nominal CLKIN coarse phase adjustment step
Coarse step of CLKIN divider phase adjustment range; common to both channels; depends on clock divider factor (CLKDIV) and sampling rate (FS).		 1 / (2 × CLKDIV × FS) s
ΔФC Typical coarse phase adjustment step error(1)
Percent variation of actual phase adjustment step relative to the nominal step (ФC). Assumes ideal 50% CLKIN duty cycle
CLKDIV = 8, FS = 250 MSPS ±6%
CLKDIV = 4, FS = 370 MSPS ±4%
(1) CLKIN duty cycles that are not 50/50% increase the coarse delay step error

7.3 JESD204B Interface Functional Characteristics

Unless otherwise noted, these specifications apply for all supply and temperature conditions.

PARAMETER DESCRIPTION AND TEST CONDITIONS VALUE
LSF Supported configurations
L = Number of lanes/converter
S = Samples per frame
F = Octets per frame 		L = 1, S = 1, F = 2
or
L = 2, S = 1, F = 1
K Number of frames per multi-frame
Configurable via SPI
L = 1, S = 1, F = 2 9 (min)
32 (max, default)
L = 2, S = 1, F = 1 17 (min)
32 (max, default)
