HT651224BRSZ

HTCSEMI · LVDS ICs · SSOP-28-208mil

HT651224BRSZ from HTCSEMI, in a SSOP-28-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 AVSS power_in Analog circuit ground.
2 RCLK_R/F input High selects an RCLK rising-edge data strobe, low selects an RCLK falling-edge data strobe.
3 REFCLK input Reference clock input for the internal PLL; a local clock must be applied to this pin for the deserializer to initialize.
4 AVDD power_in Analog circuit power supply, 3.0 V to 3.6 V (3.3 V typical).
5 RINP input Non-inverting LVDS differential receiver input, with a differential threshold of ±50 mV.
6 RINN input Inverting LVDS differential receiver input, with a differential threshold of ±50 mV.
7 PDB input Low puts the device into low-power mode, turns off the internal PLL and places DOUT0-DOUT9, RCLK and LOCK_B in high-impedance state; drive high to exit power-down.
8 NC unconnected No connection.
9 RCLK output Recovered clock output used to strobe DOUT0-DOUT9.
10 LOCK_B output Goes low when the internal PLL locks onto the embedded clock edge; high indicates loss of synchronization with outputs in high-impedance.
11 AVDD power_in Analog circuit power supply, 3.0 V to 3.6 V (3.3 V typical).
12 AVSS power_in Analog circuit ground.
13 AVSS power_in Analog circuit ground.
14 DVSS power_in Digital circuit ground.
15 DOUT9 output Parallel data output bit 9, strobed by RCLK.
16 DOUT8 output Parallel data output bit 8, strobed by RCLK.
17 DOUT7 output Parallel data output bit 7, strobed by RCLK.
18 DOUT6 output Parallel data output bit 6, strobed by RCLK.
19 DOUT5 output Parallel data output bit 5, strobed by RCLK.
20 DVSS power_in Digital circuit ground.
21 DVDD power_in Digital circuit power supply, 3.0 V to 3.6 V (3.3 V typical).
22 DVSS power_in Digital circuit ground.
23 DVDD power_in Digital circuit power supply, 3.0 V to 3.6 V (3.3 V typical).
24 DOUT4 output Parallel data output bit 4, strobed by RCLK.
25 DOUT3 output Parallel data output bit 3, strobed by RCLK.
26 DOUT2 output Parallel data output bit 2, strobed by RCLK.
27 DOUT1 output Parallel data output bit 1, strobed by RCLK.
28 DOUT0 output Parallel data output bit 0, strobed by RCLK.
