Dual 4-Channel Driver with Oscillator and

LVDS

chip, while the SEL1 pin selects the I

waveforms can be generated where the amplitude is

determined by the currents flowing into I

WEN2B, WEN3-WEN3B, and WEN4-WEN4B. The oscillator

is enabled when OSEN is high. The amplified I

the selected channel is enabled when the ENA pin is high.

The total output current is the sum of the read current, the

enabled write currents, and the oscillator current when

enabled.

Usually a voltage DAC will drive a resistor that is in series

with the I

the user to optimize the current gain for each channel.

WEN2-WEN2B, WEN3-WEN3B and WEN4-WEN4B are

LVDS input pins with 100Ω external termination. Output write

current pulses are enabled when a high is applied to the

WEN2-WEN2B, WEN3-WEN3B, or WEN4-WEN4B pin. The

write current will flow to the selected output. When SEL1 is

high I

current when low.

The RF oscillators frequency is determined by R

Ordering Information

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J Std-020B.
