Product Family
This data manual covers three devices in the TVP5150A product family: the TVP5150APBS, the TVP5150AM1PBS,
and the TVP5150AM1ZQC. The hardware for these three devices is identical. The following software changes are
the differences between these two devices. For the remainder of this document, unless otherwise noted, TVP5150A
refers to all three devices.
•
TVP5150APBS
−
ROM version 3.21
−
SECAM is masked from the autoswitch process in the default mode of register 0x04
−
Only supports ITU-R BT656.4 timing
•
TVP5150AM1PBS/TVP5150AM1ZQC
−
ROM version 4.00
−
SECAM is unmasked from the autoswitch process in the default mode of register 0x04
−
Addition of register 0x30 to select ITU-R BT656.3 or ITU-R BT656.4 timing
