CAM1000

MultiCAM-1000 has 11 focus point with a center cross-type. In D200, D80 and D90, it uses Sony ILX148 linear CCD. ILX148 has 8 segment pairs, which added 2 more based on CAM900. Recent cameras since D3000 and D5000 are using NEC D3705BMM.

This AF senosr is housed inside a 24 pin plastic SOIC package. Power supply includes 12V, 3.3V, 5V, and GND. Digital input signal contains what appears to be a 5-wire parallel port, a input master clock (MCK) shared with AE CCD and a standby signal. Output signals includes an analog Vout synchronized with ADCTRG pulse, and a R/W state signal sending to P36/TCIN pin on TMP19.

Linear Pixel Defined as follows: *Pixel Pattern: B-Bias/Dummy, I-Intermediate/Buffer, A-Active, D-Dark/Optical Black

Parallel Protocol
The 5-wire parallel interface has a sampling clock (PH7), a packet begin/end (PE0), and 3 data lines (PJ2/3/4) each for 1 bit. Data is valid at PH7 rising edge. A packet begins and ends with PE0 low, while sending 000 and 100 respectively. Each packet contains 2 3-bit information. The first is command and second for data.
