1. Updated Electrical Characteristics to add propagation delay and phase noise information.
2. Corrected SMBus to reference pin numbers for 423 instead of 823 device.
3. Removed references to OE controls that are not present on 423.
4. Added SMBus electrical characteristics
5. Added foot note about DIF input running in order for the SMBus interface to work
6. Added foot note to Byte 1 about functionality of OE bits and OE pins.
7. Corrected Block Diagram with proper OE pins indicated and PD and DIF_STOP# pins
added
8. Updated clock periods to reflect +/-100ppm input clock tolerance
(CK410B+/CK420BQ/CK505).
9. Changed SRC_Stop references to DIF_Stop references for consistency.
1. Corrected Polarity of PD pin when OE_INV = 1. PD is always active low (or PD#). This is
a difference from the 9DB803D.
