Texas Instruments (TI) has recently introduced a compact low-voltage differential signaling (LVDS) serializer and deserializer (SerDes) in a 5x5mm QFN package. This innovative solution is reported to be more than one-third smaller than competing products, making it an ideal choice for space-constrained applications such as wireless base stations, data communication backplanes, industrial systems, video equipment, and in-vehicle infotainment systems.
The SN65LV1023A serializer and SN65LV1224B deserializer are part of a 10-bit SerDes chipset that enables high-speed serial data transmission and reception at clock rates equivalent to parallel word speeds—ranging from 10MHz to 66MHz via an LVDS differential backplane. This performance translates into a throughput range of 100 Mbps to 660 Mbps, offering flexibility for various high-bandwidth applications.
At the maximum operating frequency of 66MHz, the chipset consumes less than 450mW, making it energy-efficient while maintaining high performance. It features a fast-locking synchronous mode with a lock indicator, eliminating the need for external components in the phase-locked loop (PLL). This makes the design simpler and more reliable, especially in industrial environments that operate between -40°C and 85°C. Additionally, the chip includes programmable edge flip-flops and a straight-through pinout configuration, which simplifies PCB layout and improves design efficiency.
Both the SN65LV1023A and SN65LV1224B are now available for purchase through TI and its authorized distributors. They come in a 5x5mm 32-pin leadless quad flat pack (QFN) package, with an alternative 28-pin Small Outline Package (SSOP) version also available. For bulk orders of 1,000 units, the suggested unit price is $4.60, making it a cost-effective option for designers looking to optimize both space and budget in their next-generation designs.
