GS9021 General Description

The GS9021 implements error detection and handling (EDH) according to SMPTE RP-165. Interfacing to the parallel inputs of either the GS9002, GS9022 or GS9032 serial digital encoders, the GS9021 is primarily used on the transmit end of the SDI interface. The GS9021 provides EDH insertion and extraction for 4fsc NTSC, 4fsc PAL and all component PAL and NTSC standards including 4:2:2 (13.5MHz and 18MHz luminance sampling), and 4:4:4:4.

The GS9021 generates noise immune timing signals such as horizontal sync, vertical blanking and field ID. In addition, TRS-ID correction/insertion and data blanking are implemented for all standards.

A host interface, configurable as an 8-bit parallel interface or an I²C (I²C is a registered trademark of Philips) serial interface allows for communication with a microcontroller. The interface can be used to read and/or write the complete set of error flags and override the flag status prior to re-transmission. A 5-bit flag port provides access to all error flags on dedicated pins for applications where the microcontroller is not used. The device automatically determines the operating standard, but this can be overridden through the programming interface.

GS9022 General Description

The GS9022 is a monolithic bipolar integrated circuit designed to serialize SMPTE 125M and SMPTE 244M bit parallel digital signals as well as other 8 or 10 bit parallel formats. This device performs the functions of sync detection, parallel to serial conversion, data scrambling (using the X⁹ + X⁴ +1 algorithm), 10x parallel clock multiplication and conversion of NRZ to NRZI serial data. The data rate is automatically set for SMPTE 259M data rates to 400 Mb/s. Other features include a lock detect output and an internal cable driver capable of driving two 75Ω loads.

The device requires a single +5 volt or -5 volt supply and typically consumes 650 mW of power while driving two 75 Ω loads. The 28 pin PLCC packaging assures a small footprint for the complete encoder function.
