The analog ground (AVS) pins for the analog core.
AVS should be connected to analog GND.
Notes on Pin Description:
1. All S/UNI-QUAD inputs and bi-directionals present minimum capacitive
loading and operate at TTL logic levels except: the SD, RXD+ and RXD-
inputs which operate at pseudo-ECL (PECL) logic levels
2. The RDAT[7:0], RPRTY, RSOC, DRCA4-1, RCA, DTCA4-1, TCA, TCLK and
RCLK1-4 outputs have a 4 mA DC drive capability. The TDO output has a 1
mA drive capability. All the other outputs have a 2 mA DC drive capability.
The TXD+ and TXD- outputs are met to be terminated in a passive network
and interface at PECL levels.
3. It is mandatory that every ground pin (VSS) be connected to the printed
circuit board ground plane to ensure a reliable device operation.
4. It is mandatory that every power pin (VDD) be connected to the printed circuit
board power plane to ensure a reliable device operation.
5. All analog power and ground can be sensitive to noise. They must be
isolated from the digital power and ground. Care must be taken to decouple
these pins from each other and all other analog power and ground pins.
