APPLICATIONS
SMPTE 259M serial digital receiver for composite and
component standards including 4:4:4:4 at 540Mb/s with
EDH processing; Noise immune digital sync and timing
generation; Cost effective EDH insertion and checking for
serial routing and distribution applications.
DESCRIPTION
The GS9020A is specifically designed to deserialize SMPTE
259M serial digital signals. The inclusion of Error Detection
and Handling (EDH) ensures the integrity of the data being
received from the serial digital interface (SDI). Internal 75
termination resistors allow INTERLINXTM seamless
connection with the GS9035A Reclocker or the GS9025A
Receiver, thus providing a complete high performance,
digital video input processor with EDH, digital sync signal
generation, and other system features.
The GS9020A also includes a parallel to serial converter
and NRZI scrambler to provide re-serialized, EDH
compliant data output. The EDH core implements EDH
insertion and extraction according to SMPTE RP-165. This
core also generates noise immune timing signals such as
horizontal sync, vertical blanking, field ID and ancillary data
identification. It also provides many system features such
as a FIFO reset pulse (which can be programmed to
coincide with either EAV or SAV), TRS-ID and ANC header
correction, user controlled output blanking and ITU-R-601
output clipping. The GS9020A has an IC (Inter-Integrated
Circuit, IC is a registered Trademark of Philips) serial
interface bus and an 8-bit parallel port for external access
to all error flags and device configuration bits.

1. R
PULLUP
refers to the internal pullup resistor associated with the serial data and clock inputs (see Figure 4).
2. Assuming 100
differential termination resistor as shown in figure 7. Given V
DIFFOUT

ANC_CHKSM, FLYWDIS, FLAG_MAP, RESET, CRC_MODE, FIFOE/S AND HOSTIF_MODE. To ensure reliable operation
these pins should be externally connected to GND or V
cc

NOTES
1. The serial clock rising edge should occur at the centre of the data period for optimum performance. (See Figure 1)
2. Since the GS9020A does not have a parallel clock input, it is not possible to define timing details relative to it. Instead the
GS9020A has a parallel clock output and all timing information is relative to PCLKOUT. The flag port pins (FL[4:0], F_R/W,
S[1:0]) are the only inputs where the timing details are important. The timing requirements are shown in Figure 2.
3. These times are relative to the rising edge of PCLKOUT as shown in Figure 3. Note that the data transitions at the falling
edge of PCLKOUT. T is the parallel clock period in ns.
4. The Host Interface signals, P[7:0], R/W, A/D and CS are asynchronous to the parallel clock.
