21-Bit Deserializers with Programmable
Spread Spectrum and DC Balance
_______________________________________________________________________________________

Note 1:
Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to ground,
except V
TH
and V
TL
.
Note 2:
Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are production
tested at T
A
= +25°C.
Note 3:
To provide a mid level, leave the input open, or, if driven, put driver in high impedance. High-impedance leakage current
must be less than ±10μA.
Note 4:
RxCLKOUT limits are scaled based on RxOUT_ measurements, design, and characterization data.
Note 5:
One output shorted at a time. Current out of the pin.
Note 6:
V
TH
, V
TL
, and AC parameters are guaranteed by design and characterization, and are not production tested. Limits are set
at ±6 sigma.
Note 7:
C
L
includes probe and test jig capacitance.
Note 8:
RCIP is the period of RxCLKIN. RCOP is the period of RxCLKOUT.
Note 9:
RSKM is measured with less than 150ps cycle-to-cycle jitter on RxCLKIN.
