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
