to the DDR2-667 (5-5-5) specification. All of the control and address inputs are
synchronized with a pair of externally supplied differential clocks. Inputs are latched at the
cross point of differential clocks (CLK rising and CLK falling). All I/Os are synchronized
with a single ended DQS or differential DQS- DQS pair in a source synchronous fashion.

Double Data Rate architecture: two data transfers per clock cycle
CAS Latency: 3, 4, 5, 6 and 7
Burst Length: 4 and 8
Bi-directional, differential data strobes (DQS andDQS ) are transmitted / received
with data
Edge-aligned with Read data and center-aligned with Write data
DLL aligns DQ and DQS transitions with clock
Differential clock inputs (CLK and CLK )
Data masks (DM) for write data

referenced to both edges of DQS
Posted CAS programmable additive latency supported to make command and data
bus efficiency
Read Latency = Additive Latency plus CAS Latency (RL = AL + CL)
Off-Chip-Driver impedance adjustment (OCD) and On-Die-Termination (ODT) for
better signal quality
Auto-precharge operation for read and write bursts
Auto Refresh and Self Refresh modes
Precharged Power Down and Active Power Down
Write Data Mask
Write Latency = Read Latency - 1 (WL = RL - 1)

Demodulators
MSB1210
The MSB1210 is the world’s 1
st
hybrid demodulator to receive both analog
terrestrial TV and digital TV signals. It contains the state of the art Signal Processing to
offer high quality receptionof analog terrestrial TV signals compliant with PAL B(G, PAL I
standards. It also contains a superior COFDM demodulator. It can be used in all 2K, 4K
and 8K modes with 5,6,7 and 8 MHz channels and is capable of receiving all modes of
transmission.

The device includes a high performance 11 bit A/D converter capable of accepting
direct IF at 36 or 44 MHz. It can also support low IF and ZIF signaling. Sampling rates
required for all these frequencies in OFDM channels can be generated from a single
24MHz crystal.
