GENERAL DESCRIPTION

The ADATE209 is a dual pin driver designed for testing DDR2,

DDR3, and DDR4. It can also be used for high speed SoC applica-

tions, such as testing PCI Express 1.0 and HDMI™. The device is a

three-level driver capable of high fidelity swings from 200 mV

to 4 V over a −1 V to +3.5 V range. It has rise/fall times (20% to

80%) under 120 ps for a 2 V programmed swing and 150 ps for

a 3 V programmed swing and is capable of supporting data rates

of 4.4 Gbps and 3.2 Gbps, respectively.

The device is capable of high speed transitions into and out of

termination mode. It also contains peaking/pre-emphasis circuitry.

The ADATE209 is available in an 8 mm × 8 mm, 49-ball

CSP_BGA.
