DATA SHEET
DESCRIPTION
The GS1522 is a monolithic bipolar integrated circuit
designed to serialize SMPTE 274M and SMPTE 260M bit
parallel digital signals.
This device performs the following functions:
• Sync word mapping for 8-bit/10-bit operation.
• Parallel to Serial conversion of Luma & Chroma data
• Interleaving of Luma and Chroma data
• Data Scrambling (using the X9+X4+1 algorithm)
• Conversion of NRZ to NRZI serial data (using the (X+1)
algorithm)
• Selectable DUAL or QUAD 75Cable Driver outputs
• Lock Detect Output
• 1.485Gb/s or 1.485/1.001Gb/s operation
This device requires a single 5V supply and typically
consumes less than 1000mW of power while driving two
75cables.
The GS1522 uses the GO1515 external VCO connected to
the internal PLL circuitry to achieve ultra low noise PLL
performance.

DESCRIPTION
Test Signal. Used for manufacturing test purposes only. This pin
must be tied low for normal operation.
Negative Supply. Ground for ring oscillator. This pin must be
floating for normal operation.
Control Signal Input. Input pin is AC coupled to ground using a
50transmission line.
Control Signal Input. Voltage controlled oscillator input. This pin is
connected to the output pin of the GO1515 VCO. This pin must be
connected to the GO1515 VCO output pin via a 50transmission
line.
Negative Supply. Most negative power supply connection. For
phase detector stage.
Guard Ring. Ground guard ring connection to isolate phase
detector in PLL stage.
Status Signal Output. Indicates the amount of excessive jitter on
the incoming SDI and SDI input.
Positive Supply. Most positive power supply connection. For phase
detector stage.
Loop Filter Connections.
Control Signal Input. Phase lock detect time constant capacitor.
Test Signal. Used for manufacturing test only. This pin must be left
floating in normal operation.
Most Negative Power Supply Connection . Enables the jitter
demodulator functionality. This pin should be connected to
ground. If left floating, the DM function is disabled resulting in a
current saving of 340µA.
Negative Supply. Most negative power supply connection. For loop
filter stage.
Control Signal Output. Control voltage for GO1515 VCO.
Control Signal Input. Used to provide electronic control of Loop
Bandwidth.
Positive Supply. Most positive power supply connection. For loop
filter stage.
Positive Supply. Most positive power supply connection. For input
stage.
Control Signal Input. Used to disable the sync detection function.
Logic HIGH disables sync detection. Logic LOW: 000-003 is
mapped into 000 and 3FC-3FF is mapped into 3FF for 8-bit
operation.
Input Data Bus. The device receives a 20 bits data stream running
at 74.25 or 74.25/1.001 MHz from the GS1501 HDTV Formatter or
GS1511 HDTV Formatter. Input data can be in SMPTE292M
scrambled or unscrambled format. DATA_IN[19] is the MSB (pin
103). DATA_IN[0] is the LSB (pin 128).
