Programmable IF frequency (38.9 MHz, 45.75 MHz, 32.9 MHz, 58.75 MHz,
36.125 MHz etc.)
Digital IF processing for the following standards: B/G, D/K, I, L/L', and M/N
Standard specific digital post filtering
Standard specific digital video/audio splitting
Standard specific digital picture carrier recovery:
-Alignment-free
-Quartz-stable and accurate
-Stable frequency lock at 100% modulation and overmodulation up to
150%
-Quartz-accurate AFC information
Programmable standard specific digital group delay equalization
Automatically frequency-adjusted Nyquist slope, therefore optimum picture and
sound performance over complete lock in frequency range
Standard-specific digital AGC and delayed tuner AGC with programmable tuner
take-over point
Fast AGC due to linear structure
Adaptive back porch control, therefore fast positive modulation AGC
No sound traps needed at video output
SIF output with standard-dependent pre-filtering and amplitude-controlled output
level
Optimal sound SNR due to carrier recovery without quadrature distortions
FM radio capability without external components and with standard TV tuner
Prepared for digital TV (DVB-C, DVB-T, ATSC)
I2C bus interface
7. SERIAL 64K I2C EEPROM M24C64WBN6
7.1 General Description
M24C64WBN6 is a 64 Kbit Electrically Erasable PROM. These I2C-compatible
electrically erasable programmable memory (EEPROM) devices are organized as
8192x8 bits. It
comprising a bi-directional data line and a clock line.
The M24C64WBN6 is available in the standard 8-pin (Vcc, WC, SDA (I2C data), SCL
(I2C clock), Vss,E0,E1,E2). WC pin is critcal pin. If WP is high, writing is not possible to
EEPROM. If WP is low, writing is possible to EEPROM.
7.2 Features
