ELECTRICAL CHARACTERISTICS (continued)
(V
Note 2: Defined as the DC offset shift when switching between input channels for a given output.
Note 3: Voltage Gain Accuracy for MAX458 calculated as (V
Note 4: Voltage Gain Accuracy for MAX459 calculated as (V
Note 5: All logic levels are guaranteed over the range of V
Note 6: Differential phase and gain measured with a 40 IRE (285.7mV), 3.58MHz sine wave superimposed on a linear ramp of 0 IRE
Note 7: For MAX458, step input from +2V to 0V; for MAX459, step input from +1V to 0V. All unused channels grounded and all
Note 8: Test input channel programmed to an output and grounded through a 75Ω resistor. Adjacent input is programmed to an
Note 9: Same as Note 6 above, except driven input and output are not adjacent to test input/output.
Note 10: All inputs but the test input are driven by a 10MHz 4Vp-p sine wave. All outputs except the test output are connected to driven inputs.
Note 11: Same as Note 9 above, except with test channel programmed off.
Typical values are at T

to 100 IRE (714.3mV). “The IRE scale is a linear scale for measuring, in arbitrary IRE units, the relative amplitudes of the var-
ious components of a television signal” (from the “Television Engineering Handbook”, edited by K. Blair Benson, McGraw
Hill). This system defines 100 IRE as reference white, 0 IRE as the blanking level, and -40 IRE as the sync peak. The equip-
ment used for the test signal generated 714.3mV (100 IRE) as reference white and -285.7mV (-40 IRE) as sync. The modu-
lation used was 285.7mV (40 IRE), which conforms to the EIA color signal standards.
