DESCRIPTION

DETAILS

RATE

8 Green LEDs

Displays the current sample clock rate as well as lock status. When SYNC SOURCE is set 
to INTERNAL, both the LOCK LED and the corresponding base sample RATE LED (44.1 
kHz or 48 kHz) will be lit.  When SYNC SOURCE is set to EXTERNAL (AES or WORD), the 
LOCK LED be lit when a valid clock signal ranging from 28 kHz to 216 kHz is present; if 
no signal is present or the clock is out of range, the LOCK LED will flash to indicate that 
the GENx192 is not synchronized to the clock source.
When the external clock rate falls within ± 6.0% of a nominal sample rate, the cor-
responding RATE LED will flash. When the external clock rate falls within ± 0.2% of a 
nominal sample rate, the corresponding RATE LED will light solid.  

SYNC SOURCE 

4 position rotary switch

Selects either an internal oscillator (44.1 kHz or 48 kHz) or an external clock source (AES 
or word clock).

A OUTPUTS

3 position rotary switch

Sets the sample rate for the A OUTPUTS. When an internal clock is used, the switch 
multiplies the base rate (set by SYNC SOURCE) by either 1x, 2x, or 4x. However, when an 
external clock is used, the switch can act as either a multiplier or divider, depending on 
the rate of the external clock.  For example, with an external 96 kHz clock, the GENx192 
generates 96 kHz when the A OUTPUT switch is set to 96, 192 kHz when set to 192 (x2), 
and 48 kHz when set to 48 (÷2).  See CLOCK DIVISOR RANGES for more information.

B OUTPUTS

3 position rotary switch

Sets the sample rate for the B OUTPUTS. Functions identically to the A OUTPUTS switch.

POWER SWITCH

Rocker switch

Turns the unit off and on.

DESCRIPTION

SYSTEM:

Internal Sample Rates

44.1 kHz and 48 kHz base rates, multiplied by 2x and 4x to 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz

External Frequency Range

28 kHz to 216 kHz

Clock Skew --  Any Output to Any 
Output

< 1.00%, 28 kHz to 216 kHz, any output to any output

TS-75 Word Clock Termination Sensing 

LEDs indicate condition of clock signals based on known and expected signal voltages and source and load termina-
tion conditions

Output Sense:

 

Amber > 4.3 Vpp  

 

 

4.3 Vpp ≥ Green ≥ 3.5 Vpp 

 

 

Red < 3.5 Vpp

Input Sense:

 

Amber > 4.4Vpp 

 

 

4.4 Vpp ≥ Green ≥ 1.4 Vpp 

 

 

Red < 1.4 Vpp

Clock Divisor Ranges

When an external clock falls within the frequency ranges prescribed below, the clock is divided down in order to create 
the base rate for the unit 
 

 

÷1, 28kHz to 56 kHz 

 

 

÷2, 56kHz to 112 kHz 

 

 

÷4, 112kHz to 216 kHz
