ELECTRICAL CHARACTERISTICS (continued)

(VCC = +9.75V, VEE = -5.25V, VCCO_ _ = 2.5V, SC1 = SC0 = 0, VCPHV_ = 7.2V, VCPLV_ = -2.2V, TJ = +85°C, unless otherwise noted. All tem-

perature coefficients are measured at TJ = +70°C to +100°C, unless otherwise noted.) (Note 1)

Note 15: Rising edge to rising edge or falling edge to falling edge.

Note 16: Specified amplitude is programmed. At this pulse width, the output reaches at least 95% of its nominal (DC) amplitude.

The pulse width is measured at DATA_.

Note 17: Specified amplitude is programmed. Maximum data rate specified in transitions per second. A square wave that reaches

at least 95% of its programmed amplitude may be generated at one-half this frequency.

Note 18: Crosstalk from any driver to the other three channels. Aggressor channel is driving 3VP-P into a 50Ω load. Victim channels

are in term mode with VDTV_ = 1.5V.

Note 19: Indicative of switching speed from DHV_ or DLV_ to DTV_ and DTV_ to DHV_ or DLV_ when VDLV_ < VDTV_ < VDHV_. If

VDTV_ < VDLV_ or VDTV_ > VDHV_, switching speed is degraded by approximately a factor of 3.

Note 20: Both high and low comparators are tested.

Note 21: Change in offset voltage over input range.

Note 22: Change in offset voltage with power supplies independently set to their minimum and maximum values.

Note 23: Unless otherwise noted, all prop delays are measured at 40MHz, VDUT_ = 0 to 2V, VCHV_ = VCLV_ = 1V, slew rate = 2V/ns,

ZS = 50Ω, driver in term mode with VDTV_ = 0V. Comparator outputs are terminated with 50Ω to GND at scope input with

VCCO_ _=2V. Open-collector outputs are also terminated (internally or externally) with RTERM = 50Ω to VCCO_ _. Measured

from VDUT_ crossing calibrated CHV_/CLV_ threshold to the crossing point of differential outputs.

Note 24: VDUT_ = 0 to 1V, VCHV_ = VCLV_ = 0.5V. At this pulse width, the output reaches at least 90% of its DC voltage swing. The

pulse width is measured at the crossing points of the differential outputs.

Note 25: Relative to propagation delay at VCHV_ = VCLV_ = 1.5V. VDUT_ = 200mVP-P. Overdrive = 100mV.
