DESCRIPTION

The M52390FP is a single-chip semiconductor integrated circuit which has a function to convert R/G/B signal to NTSC/PAL composite video signal and the superimpose function.

FEATURES

• LPF for chroma difference signal is built-in. Cutoff frequency control is possible by connecting a resistor externally.
• Because VCA circuit is built-in, gain control at chroma block is possible.
• Carrier leak is on a low level because of built-in high-precision modulation circuit and clamp circuit.
• Burst signal and sync signal are generated within the IC. Superimpose function
• Ys IN (control input) is used for switching 2 input signals, VIDEO IN and RGB IN.
• Because high-speed analog switch is built-in, even microscopic characters can be inserted.
• Built-in an APC circuit to adjust tint of the parent picture (VIDEO IN) and the RGB encode signal automatically. Overall functions
• A drive circuit (75W ) can be configured with one transistor by outputting the video output signal at 2VP-P.
• This device can be used for both NTSC system and PAL system.

MITSUBISHI ICs (AV COMMON) (Frequency of output at pin when 100kHz is input is set to 0dB.) (2) Setting of free run frequency In this IC, the VCXO circuit generates fsc. Therefore, set the oscillator frequency of VCXO to fsc as follows before using this IC. 1) Connect pin (VIDEO IN) to GND and set it to free run mode. 2) V4 is the voltage at pin (OFFSET R) when sync is input to pin (C.Sync IN). Apply voltage V4 - 0.5V to pin (OFFSET R). 3) Set pin (C.Sync IN) to H. (5V is applied.) 4) Set the output frequency at pin (TRAP) by adjusting the trimmer capacitor at pin (VCXO IN). (3)Setting of chroma difference LPF The frequency characteristics of the chroma difference LPF which is built in this IC can be set as shown in Fig. 1 by connecting a resistor externally to pin (fc CONT.). The group delay characteristics also change as shown in Fig. 2. (4) Setting of Y DL The group delay characteristics of color signal of RGB encode output changes by connecting a resistor externally to pin (fc CONT.). Therefore, set Y DL based on the delay volume (group delay volume derived from group delay characteristics + 40ns). In case that a trap circuit is connected to pin , take the delay from +5 to +10ns into consideration. (5) Color control characteristics Gain in chroma section can be set as shown in Fig. 3 by applying voltage to pin (COLOR CONT.). (The burst amplitude is fixed.) (6) Relation between BFP and HHK The pulse width of GFP and HHK can be set as shown in Fig. 4 by connecting DR externally to pin (HHK).
