TFP410: Can the chip support 720p at 120Hz refresh rate?

Part Number: TFP410

Tool/software:

I have come across TI's TF410 www.ti.com/.../TFP410 video driver chip and had a few questions I wanted to ask:
1. The datasheet mentions the chip's capability to generate a video stream of 1080p at 60Hz. However, there is no mention of higher refresh rates at lower resolutions. Specifically, we are wondering if it is possible to produce a video stream at 720p 120Hz using this chip.
2. Regarding the TFP410 chip's Lifecyle. the TI website says it is "Active" and all indications are that the chip will be in production and available for the next decade or so. Given that the chip is around 20 years old, does TI still recommend this part for new designs? Can we get more information on when the chip may be phased out?

Regards,
Mahdi

    Hey Mahdi,

    Yes the TFP410 can handle lower resolutions at higher refresh rates. 

    The TFP410 can get up to 165MHz pixel rate:

    pixel rate is defined as follows: Pix rate = V*H*RR*1.2

    For example 1080p at 60Hz pixel rate = (1920 *1080 *60 *1.2) = 149.3 MHz

    To do 720p 2 120Hz the pixel clock needed = 1280*720*120*1.2 = 132.7MHz which will work with this device.

    This device is still a generator of revenue for our product line, and there are no plans to EOL this part.
