ADC12DJ2700: ADC12DJ2700 device questions

Part Number:ADC12DJ2700

Hi Team,

Regarding the ADC12DJ2700 device:

1.       Datasheet p.11, V_ID (Input voltage, peak-to-peak differential), for CLK+/-, SYSREF+/-, units of V_PP-DIFF:
See enclosed pictures (from the LMK datasheet):

(Please visit the site to view this file)

Does V_PP-DIFF refer to V_ID or 2*V_ID ?

2.       Same as (1) for INA+/- on p. 11 (units of V_PP-DIFF) and V_{IN_FSR} on p.12 (units mVpp).
Both Seem to describe the same value but with different units.
Does it refer to V_ID or 2*V_ID ?

3.       SCLK, SDI, SDO, SCS are limited by VA19 (table on p. 10).
However, SCS on pin description p. 6, has a 82K PU to VD11.
Please advise.

4.       What is the tolerance for Z_T of 110ohm (datasheet p.13)?

Thanks,

Shlomi
