IQOYA SERV/LINK user manual
11.7 Global audio and clock settings
The sampling frequency, the network packet size as well as the clock source can be configured by clicking on “RAVENNA Audio-ra0”,
from the “Media” section.
The sampling frequency and the network packet size can be configured by clicking on “RAVENNA Audio-ra1”.
In case the clock source is configured to PTP , it is necessary to set the PTP clock parameters, by clicking on “PTP”, from the “Sync”
section

Hostname : This is the tname of the RAVENNA node, used to
identify the device at a network level. This name must be unique
on the network,; no spaces are allowed, no special characters.
Gateway : specify the network gateway IP address if there is one.
Default TTL : Time To Live value. It defines the number of routers
the generated frames can cross..
Audio block size : this defines the number of samples per
channel per network packet; the smaller the
frame size, the lower the latency but the more susceptible to
drop-outs. Values are from 1 to 128 samples.
Sample rate : this is the audio sample rate: 48000 Hz or 44100
Hz.
Sync Source : this defines the clock source of SERV/LINK. The
clock source can be:
● PTP: SERV/LINK can be PTP Master or slaved to PTP
● WordClock: received on the WordClock input of the card
● MADI: the card automatically synchronizes on the
detected MADI signal.
PTP Clock source : This defines the source of the PTP clock of
the card.
See “Use cases for clock configuration” below for setting the clock
parameters.
Slave only : when this option is checked, SERV/LINK is forced to
run in PTP slave mode.
In case this option is not check, the SERV/LINK card can be
elected as Master PTP depending on its priority. A device is
elected as master PTP if the priority of its PTP clock is the highest.
Domain : Time domain for PTP. This MUST be set to match the
domain number of the related PTP Grandmaster.
Prio1 : Internal PTP setting. This parameter is used to control the
priority of Grandmaster selection
Prio2 : Sames as Prio1
Announce Interval : in seconds (1, 2, 4, 8 or 16). In Slave mode,
this MUST be set to match the Announce Interval of the related
PTP master clock. In Master mode, this determines the desired
Announce Interval.
Sync interval : in seconds (0.5, 1 or 2). In Slave mode, this MUST
be set to match the Sync Interval of the related PTP master clock.
In Master mode, this determines the desired Sync Interval.
Delay request mechanism : End to End (E2E) or Peer to Peer
(P2P). This MUST be set to match the related PTP master clock.
While E2E is a more universal setting, P2P provides higher clock
sync precision but requires full
support from all participating switches (between the node and
