What was the revenue increase in the computing market in Q3 2020 compared to Q2 2020 
mited distance, small cell has become increasingly common to improve the coverage and capacity of the network. Our low-jitter high performance crystal oscillator are needed in certain modules for precision timing needs. In the CPG space, our PCI Express packet Switches and clock buffers are finding wide acceptance in many 5G boxes. We also saw strong momentum for PMOS in remote radio unit and NMOS for 1 KV for large boost power in 5G base stations to save power consumption. [Indecipherable] TVS and LDOs also saw increasing design-ins and design wins in smartphone and 5G router applications.
Lastly in the computing market, revenue increased over 7% sequentially and also 14% year-over-year to record levels as work-from-home and shelter in place continue to drive momentum in notebooks, motherboard, surfers and storage applications, in particular for our Pericom product family. This quarter we released 20 output PCI Express Gen4 and Gen5 clock buffers, building up on our previous released family of clock buffers and clock generators and enabling us to now offer the most comprehensive cost solutions for server and data center applications. This cost solutions and our frequency control products, position us well for the next major server platforms with PCI Express Gen for deployment.
Momentum for our Pericom product continued in the quarter and revenue remained at the second highest quarterly levels since the acquisition. This product continue to dominate in signal integrity space with PCI Express Gen 4 redrivers, [Indecipherable], USB 3.0, Gen 2 interface in PC and motherboard applications. We're also seeing tractions for our fully integrated active month for PCI Express Gen 4 and USB 3.2 [Phonetic] Gen 2 by 2 redriver solutions for USB Type C applications.
We also continue to increase market share for switching diodes and TVS products using desktop and mobile applications as notebook, PC business continue to be strong, primarily driven by work-from-home, remote education and e-learning demands due to COVID-19. Our USB power switch product line achieved record high quarterly revenue and we are seeing more USB Type C adoption with many design wins, using our popular crossbar switches product. We have also seen growth momentum for SBR, MOSFET, and SKY product in applications like USB Type C and power delivery and ATX power charging and adopters.
In summary, we're very pleased with another quarter of strong results and continued growth despite the current environment. Our record results in the automotive, consumer and computing market, combined with record worldwide POS are setting the stage for Diodes to potentially set a new quarterly revenue record next quarter in what is typically is down quarter. We look forward to reporting our continued progress and closing our Lite-On Semiconductor Acquisition at the end of November to further enhance our future opportunities.
With that, we'll now open the floor to questions. Operator?

Hey, everyone. Hope all is well. I want to start out asking for clarification from you, Emily. You mentioned that point of sale was up 19% versus revenue being up only 7%. But I think you mentioned that distributor channel inventory was up sequentially. I'm just trying to reconcile that difference?
Emily Yang -- Vice President, Worldwide Sales and Marketing
Right. Gary, good morning. Definitely POS increased globally 19% and Asia, is actually increased 20%, and North America and Europe increased 16%. Our channel inventory as actually decreased to our lowest ever, since the end of 2018. So it's really at the lower end that we define as a normal range.
Gary Mobley -- Wells Fargo Securities -- Analyst
Okay, miss heard that. All right, and as it relates to your gross margin outlook for the fourth quarter, roughly 36% and that's on a record quarterly revenue level. And so you've been at 37% or 38% gross mar
