Each of the 192 current outputs is designed to act as a precision high impedance current source. The MXED101 current source output supply range is from 15 to 30V. The outputs are arranged in a row on one side of the die with a pitch of 92 microns, which facilitates easy interface with the display. The MXED101 consists of an Input Register, Transfer Latch, parator, Bi-directional Shift Register, Counter, and 192 Programmable Current Outputs. The device has three 6-bit input data buses, DA(5-0), DB(5-0), and DC(5-0), to accept RGB or monochrome data. This data can be clocked through the device at a maximum speed of 55 MHz with a 5V logic supply (40 MHz with a 3.3V logic supply). The outputs of the MXED101 are arranged in three programmable interdigitized banks (A, B, and C) of 64 outputs each, a bank for each color of the RGB data (programming the output current is described in the Functional Description section). Bank A controls outputs 1, 4, 7, …, 190; Bank B controls outputs 2, 5, 8, …, 191; and Bank C controls outputs 3, 6, 9, …, 192. The MXED101 employs three methods to adjust display brightness: a global gain voltage, a 3-bit digital control for each color, and an external 10.8 KW resistor. In addition to these methods, the relative brightness of each output can be controlled by onchip pulse width modulation. A standby signal (STBY) is provided to place the display in low...
