Product Description

LMH1228 device is a 12G UHD-SDI low power dual output cable driver with integrated reclocker. It supports SMPTE video rates up to 11.88 Gbps, enabling UHD video for 4K/8K applications. With a wide range clock-and-data recovery (CDR) circuit, the on-chip reclocker automatically detects and locks to all SMPTE video rates up to 11.88 Gbps. The additional reclocked 100-Ω driver output on the host-side can be used for monitoring or signal distribution purposes.
The on-chip reclocker attenuates high-frequency jitter and fully regenerates the data using a clean, low-jitter clock. The reclocker has a built-in loop filter and does not require any input reference clock. The LMH1228 also has an internal eye opening monitor and a programmable pin for CDR lock indication, input signal detect, or hardware interrupts to support system diagnostics and board bring-up.
The LMH1228 is powered from a single 2.5-V supply. It is offered in a small footprint 5 mm × 5 mm 32-pin WQFN package. The LMH1228 is pin compatible with the LMH1208 (12G Dual Cable Driver).
