LMH1982SQE Description

Short technical summary and product information.

The LMH1982SQE from Texas Instruments is a versatile multi-rate video clock generator designed for various video applications, including 3G, HD, and SD video synchronization. This device can generate two simultaneous LVDS output clocks with selectable frequencies, supporting up to 148.5 MHz for HD clocks and 67.5 MHz for SD clocks.

 

Key features include Genlock capability, allowing synchronization to H and V sync input signals, and a Top of Frame (TOF) pulse with programmable output format. The LMH1982SQE supports cross-locking of input and output timing and offers an external loop filter for control over loop bandwidth, jitter transfer, and lock time. It can operate in free run or holdover mode upon loss of reference.

 

This clock generator operates with core supply voltages of 2.5V and 3.3V and output supply voltages of 2.5V and 3.3V. It features an LVCMOS input type and is housed in a 32-WQFN (5x5 mm) surface mount package. The operating temperature range is 0°C to 70°C.

 

Ideal for broadcast and professional video systems, the LMH1982SQE is suitable for applications such as video synchronization, SDI serializer and deserializer (SerDes) interfaces, video conversion, and video editing.
