2. Wideband Devices
These are not recommended for new designs. For alternatives, see the Si533x family of products.
2.1. Narrowband vs. Wideband Overview
The narrowband (NB) devices offer a number of features and capabilities that are not available with the wideband
(WB) devices, as outlined in the below list:
 Broader set of frequency plans due to more divisor options
 Hitless switching between input clocks
 Lower minimum input clock frequency
 Lower loop bandwidth
 Digital Hold (reference-based holdover instead of VCO freeze)
 FRAMESYNC realignment
 CLAT and FLAT (input to output skew adjust)
 INC and DEC pins
 PLL Loss of Lock status indicator
 FOS is not supported.
