Discera Inc., a maker of MEMS-based timing chips, has disclosed a new round of financing.

Existing investors provided the September round, according to Discera's new chief executive, Bruce Diamond. Diamond declined to disclose the amount raised, other than to say it was more than the $3.2 million reported in a filing with the California Department of Corporations.

Discera's products target the market for quartz-based timing products, which the company estimates to be a $3.8 billion market, Diamond said.

The San Jose company's current products, which have been in production for the last six or seven months, address about $1 billion of that market and are focused on consumer electronics, Diamond said.

Quartz-based timing products, from companies such as Kyocera Corp. and Epson Toyocom Corp., have dominated the market for several decades, but take up a lot of real estate on a device and drain a lot of power. Diamond said Discera's oscillators use about 50% less power, which lends the products well to portable devices.

Competitors Mobius Microsystems Inc., Multigig Inc., SiTime Inc. and Silicon Clocks Inc. have all received financing to find a replacement for quartz.

Prior to this round, Discera had raised $35 million from investors including 3i Group, Ardesta LLC, Horizon Ventures, Qualcomm Ventures and Scale Venture Partners.
