The crucial feature of the 59992A was support for DC-bias, and
that seems to have dictated its design.

If you have no need for DC-bias, an 8-pin microcontroller with a
stable crystal and suitable resistor networks on the outputs will
do fine.

TI measurements on top of DC-bias was important in development and
manufacturing of disk drives:  Measurement of jitter of mechanical
origin must happen on the analog side of the differential read
amplifier, which usually balances a couple of volts up for cost
reasons.

Never attribute to malice what can adequately be explained by incompetence.
