DETECT_TRS
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to select the timing mode of the device.
When set HIGH, the device will lock the internal flywheel to the
embedded TRS timing signals in the parallel input data.
When set LOW, the device will lock the internal flywheel to the
externally supplied H, V, and F input signals.
69
PCLK
Input
PARALLEL DATA BUS CLOCK
Signal levels are LVCMOS/LVTTL compatible.
SD 20-bit mode
PCLK = 13.5MHz
SD 10-bit mode
PCLK = 27MHz
72
LOCKED
Synchronous
with PCLK
Output
STATUS SIGNAL OUTPUT
Signal levels are LVCMOS / LVTTL compatible.
The LOCKED signal will be HIGH whenever the device has
correctly received and locked to SMPTE compliant data in
SMPTE mode or DVB-ASI compliant data in DVB-ASI mode.
It will be LOW otherwise.
73, 74
VCO, VCO
Analog
Input
Differential inputs for the external VCO reference signal. For
single ended devices such as the GO1525, VCO should be AC
coupled to VCO_GND.
75
VCO_GND
Output Power
Ground reference for the external voltage controlled oscillator.
Connect to pins 2, 4, 6, and 8 of the GO1525. This pin is an
output.
Should be isolated from all other grounds.
76
VCO_VCC
Output Power
Power supply for the external voltage controlled oscillator.
Connect to pin 5 of the GO1525. This pin is an output.
Should be isolated from all other power supplies.
77
LF
Analog
Output
Control voltage to external voltage controlled oscillator. Nominally
+1.25V DC.
78
CP_CAP
Analog
Input
PLL lock time constant capacitor connection. Normally connected
to VCO_GND through 2.2nF.
79
LB_CONT
Analog
Input
Control voltage to set the loop bandwidth of the integrated
reclocker.
80
CP_GND
Power
Ground connection for the charge pump. Connect to analog
GND.
