The GS1531 is a multi-standard serializer from Gennum that supports SMPTE292M, SMPTE259M-C and DVB-ASI standards. It has a 20-bit/10-bit CMOS parallel input data bus, supports 148.5MHz/74.25MHz/27MHz/13.5MHz parallel digital input, and has automatic standard detection and indication functions. It supports 1.8V core power supply and 3.3V charge pump power supply, 3.3V digital I/O power supply, JTAG test interface, and can be used in a lead-free package with a small footprint (11mm x 11mm).
The GS1531 HD‑LINX II from Gennum is a multi‑standard serializer that integrates a cable driver and an internal PLL. It accepts parallel CMOS data at 10‑ or 20‑bit widths and converts it to high‑speed serial formats for HD‑SDI, SD‑SDI and DVB‑ASI applications.
Key features include NRZ‑to‑NRZI encoding, scrambling, optional CRC and line‑number insertion, and a built‑in flywheel for noise‑immune TRS generation. The device operates from a 1.8 V core supply and a 3.3 V digital supply, and is offered in a Pb‑free 100‑ball LBGA package.
