BU1425AKV General Description

The BU1425AK / BU1425AKV are ICs which convert digital RGB / YUV input to composite (NTSC / PAL / PAL60), luminance (Y), and chrominance (C) signals, and outputs the results.

BU1425AKV Maximum Ratings

Parameter	Symbol	Limits	Unit
Applied voltage	V_DD, AV_DD	0.5 ~ + 7.0	V
Input voltage	V_IN	0.3 ~ IOV_DD + 0.3	V
Storage temperature	Tstg	55 ~ + 150
Power dissipation	Pd	1350¹	mW

* 1 Reduced by 11mW for each increase in Ta of 1 over 25.
* 1 When mounted on 120mm 140mm 1.0mm glass epoxy board.
* Operation is not guaranteed at this value.
Not designed for radiation resistance.

BU1425AKV Features

Input clocks supported
      27.0 / 13.5MHz
      28.636 / 14.318MHz
      28.375 / 14.1875MHz
      35.4695 / 17.73475MHz
24-bit RGB and 16-bit YUV input signals are supported.
Both master and slave systems are supported.
9-bit high-speed DAC is used for DAC output of composite VIDEO, Y, and C signals.
Internal 8-color OSD output function is provided.
FSC-TRAP on the Y channel can be turned on and off.
C channel is equipped with an internal chrominance band-pass filter in addition to the U.V. lowpass filter.
5V single power supply, low power consumption (0.4W typ.)
Y and C output can be turned off (the power consumption with Y and C off is 0.25W typ.).
In the Master mode, applying 3.3V to the I / O VDD and 5.0V to other VDDs produces HSY and VSY output with an amplitude of 3.3V. This enables direct connection to LSIs that use a power supply voltage of 3.3V. (The clock output for the OSD has a fixed amplitude of 5.0V.)
In the Slave mode, applying voltage to the I / O VDD only, and applying 0V to other VDDs, enables a current consumption of 0 even when RGB DATA, HSY, VSY, and OSD DATA are in the active state.
