Note 1:
Specifications at -40
°
C are guaranteed by design and characterization.
Note 2:
Measured with PECL outputs unterminated.
Note 3:
OPAMP specifications met with 10k
load to ground or 5k
load to V
CC
(POLAR = 0 and POLAR = V
CC
).
Note 4:
PFD/CP currents are measured from pins OPAMP+ to OPAMP-. See Table 3 for gain settings.
Note 5:
AC characteristics are guaranteed by design and characterization.
Note 6:
Measured with 50% VCO input duty cycle.
Note 7:
Random noise voltage at op amp output with 800k
resistor connected between VC and OPAMP-, PFD/CP gain (K
PD
) =
5μA/UI, and POLAR = 0. Measured with the PLL open loop and no REFCLK or VCO input.
Note 8:
Spurious noise voltage due to PFD/CP output pulses measured at op amp output with R
1
= 800k
, K
PD
= 5μA/UI, and
compare frequency 400 times greater than the higher-order pole frequency (see
Design Procedure
).
Note 9:
PSR measured with a 100mVp-p sine wave on V
CC
in a frequency range from 100Hz to 2MHz. External resistors R
1
matched
to within 1%, external capacitors C
1
matched to within 10%. Measured closed loop with PLL bandwidth set to 200Hz.
Note 10:
The PLL 3dB bandwidth is adjusted from 15Hz to 20kHz by changing external components R
1
and C
1
, by selecting the inter-
nal programmable divider ratio and phase-detector gain. Measured with VCO gain of 220ppm/V and C
1
limited to 2.2μF.
Note 11:
Measured at BW = 20kHz. When input jitter frequency is above PLL transfer bandwidth (BW), the jitter transfer function rolls
off at -20dB/decade.
