Notes: 1. Unless otherwise specified: VAA = –5V ± 5%, VSS = –5 V ±10%, VTT = –2V ± 5%, VFS = 1 V pk–pk, TCASE = 0 to +85 °C
2. See the "Power Supplies, Ground and Bypassing" section later in this datasheet for discussion of power supplies.
3. The ECL reference input establishes the switching point for the ECL line receivers used at the DATA, BLANK, and
SELECT inputs. (See Figure 1.) IECLREF is the current required to change the internal ECLREF value by about ±200 mV.
4. Values shown are for differential clock drive, and apply to both CLOCK and CLOCK inputs. For single-ended drive,
the HIGH level should be at least (VECLREF +0.5) volts, but must not exceed –700 mV. The LOW level should be
(VECLREF –0.5) volts, but must not go below VTT, where VTT is the ECL termination voltage (nominal VTT = –2 V).
5. VOUT(MAX), VOUT(MAX), VOUT(MIN), VOUT(MIN) represent the limits on the absolute output levels, including offset.
6. Blanking interval is the voltage change (as a percentage of the full-scale output swing) added to VFS when BLANK is asserted.
7. The BLANK DISABLE input turns OFF the blank current (DVBLANK = 0) when held at AGND, and turns it ON when pulled to VAA.
8. Full-scale symmetry is a measure of the balance between VOUT and VOUT. For a full-scale input change (00000000 –> 1111111),
␣ ␣ ␣ ␣ the change in VOUT will match the change in VOUT to within ± 4 mV (1 LSB @ 1 V peak-to-peak).
9. The VFS temperature coefficient is determined primarily by the external reference and loop control op amp.
