Quad, Low-Power, 1200Mbps
ATE Driver
General Description
The MAX9977 quad, low-power, high-speed, pin-elec-
tronics driver includes, for each channel, a three-level
pin driver. The driver features a wide voltage range and
high-speed operation, includes high-impedance and
active-termination (3rd-level drive) modes, and is highly
linear even at low voltage swings.
The MAX9977 provides high-speed, differential control
inputs with internal 50Ω (100Ω LVDS) termination resistors
that allow compatibility with 1.8V and 3.5V terminated
0.4V_P-P CML, reducing the discrete component count
required on the circuit board. The MAX9977AD has no
internal termination.
A 3-wire, low-voltage, CMOS-compatible serial interface
programs the low-leakage and tri-state/terminate opera-
tional configurations of the MAX9977.
The MAX9977’s operating range is -1.5V to +6.5V (con-
sult factory for other operating ranges), and features a
maximum power dissipation of only 0.8W per channel.
The device is available in a 100-pin, 14mm x 14mm
x 0.1mm body, and 0.5mm pitch TQFP. An exposed
8mm x 8mm die pad on the top of the package facili-
tates efficient heat removal. The device is specified to
operate with an internal die temperature of +60°C to
+100°C, and features a die temperature monitor output.
