13 / 24 page ![]() Production Data WM8143-10 Wolfson Microelectronics PD.Rev 3f June 98 13 MODE DESCRIPTION CDS AVAIL- ABLE MAX. SAMPLE RATE SENSOR INTERFACE DESCRIPTION TIMING REQUIRE- MENTS REGISTER CONTENTS WITH CDS REGISTER CONTENTS WITHOUT CDS* 1 Colour Yes 2MSPS Three input channels (R, G, B) are sampled in parallel at max. 2MSPS. The sampled data is multiplexed into a single data stream before the internal ADC, giving an internal serial rate of max. 6MSPS MCLK max. 12MHz. MCLK: VSMP ratio is 6:1 Setup Reg. 1: 03(H) Setup Reg. 1: 01(H) 2 Monochrome Yes 2MSPS One input channel is continuously sampled. The internal multiplexer is held in one position under control of the user. Identical to Mode 1 Setup Reg. 1: 07(H) Setup Reg. 3: bits b[7-6] define which channel is sampled Setup Reg. 1:05(H) Setup Reg. 3: bits b[7-6] define which channel is sampled 3 Fast Monochrome Yes 4MSPS Identical to Mode 2 except that max. sample rate is 4MSPS MCLK max. 12MHz. MCLK: VSMP ratio is 3:1 Identical to Mode 2 plus Setup Reg. 3: bits b[5-4] must be set to 00(H) Identical to Mode 2 4 Max. Speed Monochrome No 6MSPS Identical to Mode 2 except that max. sample rate is 6MSPS MCLK max. 12MHz. MCLK: VSMP ratio is 2:1 Not applicable Setup Reg. 1:45(H) Setup Reg. 3: bits b[7-6] define which channel is sampled 5 Slow Colour Yes 1.5MSPS Identical to Mode 1 except that max. sample rate is 1.5MSPS MCLK max. 12MHz. MCLK: VSMP ratio is 8:1 Identical to Mode 1 Identical to Mode 1 6 Slow Monochrome Yes 1.5MSPS Identical to Mode 2 except that max. sample rate is 1.5MSPS MCLK max. 12MHz. MCLK: VSMP ratio is 8:1 Identical to Mode 2 Identical to Mode 2 * Only indicates relevant register bits Table 3 WM8143-10 Mode Summary |
