Table 5. CO PLL Specifications
Unless otherwise noted, typical specifications apply for VCC=5.0 V, temperature=25×C, nominal process and bias
current. Maximum and minimum performance is with VCC ±5%, -40 =< T

<1>Input and output impedance measured with 50kW from OSCPB to Vcc and OSCNB to Vcc
<2>For inband noise, phase noise at multiples of 4.3125kHz will rms add to degrade the inband SNR. Similarly, for out of band signals,
e
phase noise will rms add depending on the offset between the carrier and the band of interest to reduce the SNR. For example,
noise contributions on carriers from 34 to 127 will rms add to degrade the SNR on the edge of the US band (carrier 26).
